It has been suggested to break out this page into seperate pages in the migration category. Thoughts? Talk page[http://wiki.zimbra.com/index.php?title=Talk:User_Migration]
+
First, note that you'll want to create accounts in Zimbra first before you do the migration. If you want to do it in one shot, read [[Bulk Provisioning]].

Migration from one mail system to another is often painful. It can result in a user having to look in two different places to find mail, or in the worst case mail disappearing.
+
Migrating your users means you're going to have to deal with [[Mail Migration|mail]],  [[Calendar and Contacts Migration|calendar, contacts]]  and [[Password Migration|passwords]]. This page used to be one monolithic monstrosity -- but has now been broken down into separate pages:
  
Copying the contents of one mail system to another often seems like a good idea, that way if anything goes wrong at least the old mail is still available. Ideally you know exactly what you are going to do at the start, you move everything across, and then you kill the old mail system (or at least hide it from mail clients).  That way users are not confused by having two sets of identical folders.

In reality, you may have a period of overlapping mail servers.  After user data has been migrated to Zimbra, users can access their mail via the web client without any additional setup until their mail client has been configured to access the Zimbra server.

== from IMAP ==
 
 
 
=== using imapsync (Recommended Method) ===
 
 
 
Currently, the recommended method for migrating users to Zimbra from an existing IMAP server is with the [http://freshmeat.net/projects/imapsync/ imapsync] tool written by Gilles Lamiral.  When in doubt, please refer to the documentation for your version of imapsync for up-to-date options and settings.
 
 
 
GertThiel originally posted [[Guide_to_imapsync|this guide]] to the zimbra forums.
 
 
 
==== from Kerio Mail Server (IMAP) ====
 
 
 
Only mail can be migrated at the moment. Refer to "Migrating from an existing IMAP server" for instructions on how to setup imapsync.
 
 
 
Using the following imapsync command to migrate emails from a single user to zimbra
 
 
 
    perl imapsync --buffersize 8192000 --nosyncacls --subscribe --syncinternaldates \
 
    --host1 kerio.host.com --user1 user@host.com --password1 keriopasswd --sep1 "/" --prefix1 "" \
 
    --host2 zimbra.host.com --user2 user@host.com --password2 zimbrapasswd
 
 
 
==== from Dovecot ====
 
 
 
See [[User_Migration_From_Dovecot_With_External_LDAP]]
 
 
 
=== using YippieMove (Commercial Method) ===
 
 
 
Note: this was probably originally added by someone from YippieMove ([[User:Gettyless]])
 
 
 
[http://www.yippiemove.com YippieMove] is a SaaS for email migration. The service allows you move between any two email providers that supports IMAP, including Zimbra. No download is required and all transfers are performed on their servers. YippieMove charges $14.95 per account transfered (volume discount available).  A screencast is available [http://yippiemove.com/video/quick-introduction.html here].
 
 
 
== POP3 ==
 
 
 
=== pop2imap ===
 
 
 
pop2imap is a tool used to get a pop inbox and syncronise it to an IMAP folder. You can get it from [http://freshmeat.net/projects/pop2imap/]
 
 
 
It is very similar to imapsync above.
 
 
 
    pop2imap  \
 
    --host1 some.pop.com.au --user1 yourAccount --passfile1 yourPasswordFile \
 
    --host2 zimbra.imap.com.au --user2 yourZimbraAccount --passfile2 yourZimbraPasswordFile \
 
    --folder MyOldPOPMail
 
 
 
Will copy the INBOX on your pop account to MyOldPOPMail folder.
 
 
 
There are some problems with pop2imap though.
 
 
 
* It will not create the folder, you must have that manually created
 
* It does not support SSL, however this is easy to do with "stunnel" - providing the SSL tunnel to the server
 
* It downloads all of the messages first to get headers, although some pop servers do this well, many do not and this is a very time consuming operation. Modifications to the script are simple to skip this step and force a copy of the mail (technically no longer a sync, but a straight copy).
 
 
 
=== imap_tools ===
 
 
 
Also check this out...
 
http://www.athensfbc.com/imap_tools/
 
 
 
it has batch mode with lists built in for all activities...POP3-IMAP, IMAP-IMAP...
 
 
 
== from Exchange ==
 
 
 
There are a least two ways to migrate the content of the individual MS Exchange user. First, is to use the Zimbra Migration Wizard. Second, is to export the contents of the MS Exchange folders to a .pst file and import them using the Zimbra PST Import Wizard.  A third option is to export the MS Exchange data to a .pst file and restore it once the Zimbra profile is created for a corresponding Zimbra user either through the Zimbra Connector for Outlook or through IMAP.
 
 
 
See forums: [http://www.zimbra.com/forums/showthread.php?t=2627 Migration from Exchange]
 
 
 
Information on using the Zimbra Exchange Migration Wizard can be found in the [http://www.zimbra.com/docs/ne/latest/migration_wizard_for_exchange_installation_guide/ Migration Wizard for Exchange Installation Guide].
 
 
 
== from Outlook ==
 
 
 
If you are using Outlook without Exchange, you can import the local mail folders directly into Zimbra with the  [http://www.zimbra.com/docs/ne/latest/import_wizard_for_outlook_guide/ PST Import Wizard].
 
 
 
== from Lotus Notes/Domino ==
 
 
 
Lotus Notes/Domino to ZCS can be found in the [http://www.zimbra.com/docs/ne/latest/migration_wizard_for_domino_installation_guide/ Migration Wizard for Domino Installation Guide]
 
 
 
== from iMail  ==
 
 
 
The first step is to export the users information including the password. I used [http://www.stalker.com/CGMigration/CGIMail.html this] utility
 
for CommuniGate Pro which creates a fixed length file. I then coverted it to a Tab-Delimited file with [http://files.twihd.com/EDC.exe this utility] so that I could use the [[Bulk Create]] process. After you create your Domains and provision the accounts, turn on IMAP4 for iMail and use the IMAP migration process.
 
 
 
== from mbox files ==
 
 
 
The mbox file format is commonly used by many programs, most notably sendmail.  The advantage of migrating from mbox files is that no passwords or special accounts are needed.  There are several scripts that people have submitted to the wiki:
 
 
 
* [[Mbox to maildir with Python]]
 
* [[Mbox to SMTP with Perl]] - forward from a mbox file to the designated address, while preserving attachments
 
* [[Mbox to maildir with Perl]] - Perl script to migrate a Kmail mbox store to IMAP. Change check_file for evolution
 
 
 
 
 
===mbox > Maildir > Zimbra hash-dirs===
 
 
 
If the mbox file can be converted to maildir format, you can use the [http://wiki.zimbra.com/index.php?title=Zmmailbox zmmailbox] utility to add messages to a user's mailbox.  This will preserve the original time and date information, and will allow administrators to sort the mail into folders giong through IMAP.

== from Thunderbird Local Folders ==
 
 
 
=== lots of local folders => mbox => dovecot => imapsync ===
 
 
 
The easiest way I found for importing a lot of Thunderbird local folders is to set up a temporary dovecot server, convert the thunderbird mail stores to linux mbox mailstores and then imapsync it from the temp server to the zimbra server:
 
 
 
* Install dovecot on a temporary server. On Debian etch: apt-get install dovecot-imapd, and then edit /etc/dovecot.conf and set the protocols to include imap. Restart dovecot. That is enough for our purposes.
 
* Download the nstouwimap script here: http://www.cs.rice.edu/~dwallach/nstouwimap/. It will be used to convert Thunderbird mailboxes to mbox files that can be read by dovecot.
 
* Copy All the local folders from all users to the server.
 
* Create a transfer user on the dovecot server.
 
* In the user's home directory, create a mail folder: /home/transferuser/mail.
 
 
 
* For each mailbox, do the following (this can be scripted):
 
** Clear the old mail folder on the server: rm -rf /home/transferuser/mail/*
 
** Run nstouwimap /path/to/user/LocalFolders /home/transferuser/mail to convert the Local Folders to the transfer user's dovecot mailbox.
 
** Run imapsync to transfer the account over to zimbra.

== Migrating User Password from Shadow Password to Zimbra==
 
 
 
Basically we will use the hash password from /etc/shadow. Get the hash values in between the first and second colon only. Eg:
 
 
 
user1:'''$1$MWAOIgPB$skcX.nKYV9JSctTR60uat/''':13780:0:99999:7:::
 
 
 
Then run this as user zimbra.
 
 
 
<pre>
 
zmprov ma user1@domain userPassword '{crypt}$1$MWAOIgPB$skcX.nKYV9JSctTR60uat/'
 
</pre>
 
 
 
A simple batch script to migrate bulk shadow password into zimbra password as below:
 
 
 
<pre>
 
#!/usr/bin/perl
 
# Usage: as root  # ./shadow2zm.pl /etc/shadow > shadow.zm
 
#        as zimbra # zmprov < shadow.zm
 
 
 
$domain="my.domain.com";
 
 
 
while(<>) {
 
    chomp;
 
    my ($uname,$pass) = split(/:/);
 
 
 
    print qq{zmprov ma $uname\@$domain userPassword '{crypt}$pass'\n};
 
    print qq{\n};
 
}
 
</pre>

= Calendar and Contacts Migration =
 
 
 
If your mail migration strategy doesn't cover contacts and calendar, you can import via the REST (REpresentational State Transfer) [http://en.wikipedia.org/wiki/Representational_State_Transfer] interface.  (Currently, contacts and calendar are only imported with the Exchange migration tool and the PST Import Wizard, so this applies to most IMAP migrations).
 
 
 
== Overview ==
 
 
 
The basic procedure is this:
 
 
 
# Export calendar or contact data from your existing server into a csv or ics file
 
# Migrate that data file to a host that can access the zimbra server
 
# Use the REST interface to insert the data into Zimbra
 
 
 
== REST overview ==
 
 
 
Today, within the Zimbra Collaboration Suite we have a number of different server-side URLs that our client accesses to download an attachment, export contacts as CSV, export a calendar as an ICS, file etc. We are also adding sharing (what would collaboration be without sharing, after all) of calendars, contacts, etc. Not only within a particular Zimbra community, but between Zimbra communities and the public at large.
 
 
 
In order to facilitate this, we are coming up with a clean, consistent URL interface to all our resources. The best way to describe this is with some examples.
 
 
 
Lets say I want access to my calendar folder from within iCal. The URL would look like:
 
 
 
  <nowiki>http://server/zimbra/user/roland/calendar</nowiki>
 
 
 
The default format on calendar folders is ICS, so no need to specify the format.
 
 
 
Lets say I want to export my contacts folder so I can import them into another account:
 
 
 
  <nowiki>http://server/zimbra/user/roland/contacts</nowiki>
 
 
 
Contact folders have a default type of CSV, so like calendars, no need to specify the format.
 
 
 
How about an RSS feed of unread messages in my inbox:
 
 
 
  <nowiki>http://server/zimbra/user/roland/inbox.rss?query=is:unread</nowiki>
 
 
 
By specifying an extension of ".rss" on the inbox folder, the server will automatically generate an RSS feed on it. Adding the "query" parameter lets me further refine what gets returned. You can also specify "?fmt=rss" instead of using the ".rss" extension if you'd like. You can also use the encoding for double quotes, %22  (For example, '''inbox.rss?query=%22is:unread%22''')
 
 
 
Lets do something a little more interesting. How about a zip file containing all messages in my talks/ajax folder:
 
 
 
  <nowiki>http://server/zimbra/user/roland/talks/ajax.zip</nowiki>
 
 
 
The server zips them all up and returns the zip file.
 
 
 
Another interesting example is say you have created a public calendar that you want to share with everyone. Once you have granted access to the calendar, it is up to the consumer to chose what format they want to view it in:
 
 
 
  <nowiki>http://server/zimbra/user/roland/calendar/talks.ics</nowiki>
 
  <nowiki>http://server/zimbra/user/roland/calendar/talks.html?view=month</nowiki>
 
  <nowiki>http://server/zimbra/user/roland/calendar/talks.atom</nowiki>
 
  <nowiki>http://server/zimbra/user/roland/calendar/talks.xml</nowiki>
 
  <nowiki>http://server/zimbra/user/roland/calendar/talks.txt</nowiki>
 
 
 
How about accessing another user's calendar/folder? Once they grant you access, you can use the same exact syntax:
 
 
 
  <nowiki>http://server/zimbra/user/janie/holidays.ics</nowiki>
 
 
 
One last interesting example to leave you with. Lets say you have a friend at widgets.com who you know is running Zimbra and who has shared their calendar with you, but you don't know the name of their public Zimbra server. As long as they publish some DNS SRV records for _zimbra._tcp.widgets.com, then you can access it directly from your Zimbra without needing to know his server's address:
 
 
 
  <nowiki>http://server/zimbra/user/friend@widgets.com/calendar</nowiki>
 
 
 
This last format (user@domain.com) is also necessary when accessing resources in a non-default domain on your local Zimbra server.
 
 
 
== REST file formats ==
 
 
 
see [[REST_File_Formats]]
 
 
 
== Importing into Zimbra ==
 
 
 
We've added the ability to update/create content by POST'ing content to REST urls. GETs continue to remain read only, with no side-effects (as they should be).
 
 
 
For example, you can POST an RFC822 formatted message to your inbox REST url to append messages to the inbox folder. Using the popular curl program, this would look like the following:
 
 
 
  <nowiki>curl -u schemers:password --data-binary @/tmp/rfc822.txt https://server/service/home/schemers/inbox</nowiki>
 
 
 
Note, you currently have to use /service/home for POSTs instead of /zimbra/home, because /zimbra/home issues a redirect, which isn't allowed with POSTs. We'll be fixing that in an upcoming release.
 
 
 
Other items that can be updated this way are calendar appointments (ICS), and contacts (csv and the new vcf (vCard) format):
 
 
 
  <nowiki>curl -u username:password --data-binary @/tmp/new.csv http://server/service/home/username/contacts?fmt=csv</nowiki>
 
 
 
  <nowiki>curl -u username:password --data-binary @/tmp/new.ics http://server/service/home/username/calendar?fmt=ics</nowiki>
 
 
 
  <nowiki>curl -u username:password --data-binary @/tmp/new.vcf http://server/service/home/username/contacts?fmt=vcf</nowiki>
 
 
 
The full user name (user@domain.com) is required when importing to resources on a non-default domain on your local Zimbra server.
 
 
 
NOTE - this works for resource accounts as well.
 
 
 
The target "contacts" in the above command corresponds to the actual folder name on the Zimbra server, rather than a service.  This means that you can import to user-defined folders by specifying the appropriate target name in the command.  If you have created a folder named "SharedContacts", for example, the command to import into this folder would be
 
 
 
  <nowiki>curl -u username:password --data-binary @/tmp/new.csv http://server/service/home/username/sharedcontacts?fmt=csv</nowiki>
 
 
 
 
 
On later version's (such as 5.0.10+) instead of --data-binary, you should use --upload-file.
 
 
 
For example:
 
curl --insecure -u admin:password --upload-file /tmp/test.csv
 
https://server/service/home/test1@domain.com/contacts?fmt=csv
 
 
 
Alternatively, you can use zmmailbox pru:
 
zmmailbox -z -m test1@domain.com pru /Contacts /tmp/test.csv
 
 
 
== Migrating Contacts ==
 
 
 
=== Eudora ===
 
* In Eudora, select the Address Book that you wish to import to Zimbra. (Select Tools/Address Book) and then Click on the correct Book.
 
* Select File/Save As, Save as type: CSV Files (*.csv) and type in an appropriate file name. Click Save
 
* Open Notepad, Open the file.csv that you saved in step 2.
 
* Insert the following line EXACTLY. (Must be the first line in the file.) <tt>nickname,email,fullName,firstName,lastName,homeStreet,homeCity,homeState,homeCountry,homePostalCode,homePhone,homeFax,homePhone2,homeURL,company,jobTitle,workStreet,workCity,workState,workCountry,workPostalCode,workPhone,workFax,workPhone2,workURL,email2,otherPhone,otherURL,notes</tt>
 
 
 
* (Make sure to press enter after the above line and save and close notepad.)
 
* Login to Zimbra, and go to Options/Address Book, Click Browse and select the file. Click import.
 
* Select the address book to import into or select New to create new address book. Wait until box in bottom left hand corner says import complete.
 
* Click Address Book and make sure the contacts imported.
 
 
 
=== Thunderbird ===
 
 
 
* Download Dawn Here: http://mysite.verizon.net/zakharin/software/Dawn/
 
* Use Dawn Wizard to import contacts into Outlook.
 
* Run the Outlook Import Wizard to import into Zimbra.

users and passwords go in a text file userlist.txt in the format: username|password.
 
 
 
With some versions of wget you may need to specify the username and password as command line arguements (ie --http-passwd=thepass --http-user=user@dom.com) instead of in the URL (ie https://usersname:pass@theurl).  If you are getting the error Bad Port, then give this a try.
 
 
 
== Copy Calendar From One Zimbra User to Another ==
 
In this example we will export a calendar called "LPO calendar" from one user
 
to another user and name it "LPO" in the destination account.
 
 
 
* Export the calendar "LPO calendar" from user SRC_USER:
 
<nowiki>[root@zimbra ~]# curl -u admin 'https://zimbra:7071/home/SRC_USER/LPO%20calendar?fmt=ics' > LPO.ics</nowiki>
 
 
 
* Adjust all the meeting organizer addresses. If you don't do this, the destination user will see the appointments, but can not edit them.
 
<nowiki>[root@zimbra ~]# cat LPO.ics | sed 's/SRC_USER@/DST_USER@/g' > LPO-dest.ics</nowiki>
 
 
 
* Create empty calendar in destination user account.
 
<nowiki>[root@zimbra ~]# su - zimbra -c 'zmmailbox -z -m DST_USER createFolder --view appointment /LPO'</nowiki>
 
 
 
* Import modified ical data into new calendar.
 
<nowiki>[root@zebra ~]# curl -u "admin" --data-binary @LPO-dest.ics 'https://zimbra:7071/home/DST_USER/LPO?fmt=ics'</nowiki>
 
 
 
 
 
== Copy All Messages, Contacts, Calendars, and Mail Filters ==
 
 
 
I have written a script, which can be run in batch, to copy user data between servers or between mailboxes.  This will copy contacts and calendars from every folder no just /Contacts and /Calendar.  I used this script two times to copy pretty much everything important when migrating from 4.5.8 to 5.0.2.  It doesn't support shared folders, task lists, documents, briefcase, and some other things (I recreated shared folders manually with zmmailbox) but support could be added given enough motivation :)
 
 
 
[http://sourceforge.net/projects/zcstools/ ZCS Tools] currently contains these Migration scripts written in Python/Bash.  These scripts are packaged as zimbraMigration-0.x and require imapsync to be installed.
 
 
 
== Import distribution list ==
 
I wrote a simply bash script to migrate distribution lists from one Zimbra server
 
to another it creates a provisioning script for each list.
 
 
 
<pre>myPath=$(pwd)
 
/opt/zimbra/bin/zmprov gadl | while read listname;
 
do
 
  echo "/opt/zimbra/bin/zmprov cdl $listname" > $myPath/$listname
 
  /opt/zimbra/bin/zmprov gdl $listname | grep zimbraMailForwardingAddress >  $myPath/$listname.tmp
 
  cat $myPath/$listname.tmp | sed 's/zimbraMailForwardingAddress: //g' |
 
  while read member; do
 
    echo "/opt/zimbra/bin/zmprov adlm $listname $member" >> $myPath/$listname
 
  done
 
  /bin/rm $myPath/$listname.tmp
 
done</pre>
 
 
 
= Migrating Sieve Filter Rules =
 
 
 
You have a few options to migrate Sieve rules.  Generally you can take existing rules and then just dump them into the account attribute zimbraMailSieveScript.  The server will be able to process these rules.  However, if you intend to enable the client to edit the rules you will need to make sure they conform to a ZCS-specific set of characteristics.  There are two ways to do this.
 
 
 
== Using zmmailbox addFilterRule ==
 
 
 
Within the zmmailbox command there is a "addFilterRule" command.  This allows you to add a named filter to a particular user.  Its usage defines the parameters that ZWC can understand for editing.  Given that for any migration scenario you'll likely end up parsing the rules, this will let you reconstruct the rules in a syntax ZWC understands.  You will need to find a "name" for each rule.  It could be as simple as "rule1", "rule2", etc.
 
 
 
Here's the usage for addFilterRule
 
<code>
 
[zimbra@qa03 ~]$ zmmailbox help filter
 
 
 
  addFilterRule(afrl)                    add filter rule
 
 
 
  deleteFilterRule(dfrl)                add filter rule
 
 
 
  getFilterRules(gfrl)                  get filter rules
 
 
 
  modifyFilterRule(mfrl)                add filter rule
 
 
 
  {conditions}:
 
    header "name" is|not_is|contains|not_contains|matches|not_matches "value"
 
    header "name" exists|not_exists
 
    date before|not_before|after|not_after "YYYYMMDD"
 
    size under|not_under|over|not_over "1|1K|1M"
 
    body contains|not_contains "text"
 
    addressbook in|not_in "header-name"
 
    attachment exists|not_exists
 
 
 
  {actions}:
 
    keep
 
    discard
 
    fileinto "/path"
 
    tag "/tag"
 
    mark read|flagged
 
    redirect "address"
 
    stop
 
 
 
</code>
 
Also, for add filter rule:
 
mbox> afrl
 
usage:
 
 
 
  addFilterRule(afrl)          [opts] {name}  [*active|inactive] [any|*all] {conditions}+ {actions}+
 
    -a/--after <arg>            add after filter-name
 
    -f/--first                  add as first filter rule
 
    -l/--last                    add as last filter rule
 
    -b/--before <arg>            add before filter-name
 
 
 
 
 
Each zmmailbox script invokes a Java VM (just like zmprov).  So you'll want to create a script to be loaded into zmmailbox.  That script would look something like
 
<code>
 
<br>
 
adminAuthenticate ...<br>
 
selectMailbox user1 ...<br>
 
addFilterRule rule1 header "from" contains "kevin" discard<br>
 
addFilterRule rule2 ....<br>
 
...<br>
 
selectMailbox user2<br>
 
addFilterRule ....<br>
 
...<br>
 
 
 
</code>
 
Then you can run it via <code>zmmailbox < scriptname</code>.
 
 
 
== Processing a Sieve script and inserting it via zmprov ==
 
 
 
Alternately you can process the existing Sieve scripts to conform to ZCS expectations and then insert the whole script via <code>zmprov ma account zimbraMailSieveScript ....</code>.  You'll need to restrict the entered rules to the Sieve commands as documented above (if ZWC or ZCO are expected to edit them).  Each filter rule will need a comment above it; this comment is the filter's name as identified in addFilterRule.  Creating one or two simple rules using the web client will give you a framework for the created rule.

First, note that you'll want to create accounts in Zimbra first before you do the migration. If you want to do it in one shot, read Bulk Provisioning.

Migrating your users means you're going to have to deal with mail, calendar, contacts and passwords. This page used to be one monolithic monstrosity -- but has now been broken down into separate pages:
