Using the Zimbra Migration Wizard

Even though the migration wizard can be run from start to finish without stopping, Zimbra recommends that after the accounts are migrated, you stop. Before proceeding, change the mail relay information to point to the Zimbra server instead of the Exchange server. This will prevent any lost mail while the files are being imported.

Note: After the files have been imported to the Zimbra server, verify that the import was successful before deleting the Exchange accounts.

How to Migrate Accounts and Import Email

From the Zimbra Administration Console display bar, click the Migration Wizard icon to download the Zimbra Migration Wizard executable to your computer.


Click Migration Wizard.exe , to open the wizard. The Welcome dialog appears. Click Next to continue.
On the Import Destination dialog, enter the following
Host name . This is the host name of the Zimbra server.
Admin Port . The port that admin services is running on is 7071.
Username and Password . This is the name and password of the administrator account on the Zimbra server.

Click Next .

In the Destination Domain dialog, select the Zimbra domain name where accounts will migrate.

Note: If you create the domain name after you started the wizard, click Refresh Domains to update the list from the Zimbra server.

Click Next .

To continue and begin the import, in the MAPI Logon dialog, identify the MAPI profile you created for use with the Zimbra Migration Wizard to conduct the migration.

Click Launch Profile Chooser , to launch a standard Windows dialog box from which you can either choose an existing MAPI profile, or create a new one, as described in the Microsoft Office documentation.

Click Next .

In the Source and Destination Mailboxes dialog, define the users to be migrated to the Zimbra server. Choose one of the following ways to select users:
Object Picker , to select specific users to migrate. Go to step a.
Query Builder , to select groups of users to migrate. Go to step b.

Note: The Object Picker is a Windows standard dialog. For Help on how to complete the dialog boxes, click the ? on the dialogs.

Click Object Picker , to select specific accounts to migrate.
In the dialog, the Object Type is preconfigured with, Users. This cannot be changed.
Click Locations , to select the domain from which to select the accounts.
In the Enter object names text box, type the user names or partial user names and click Check Names. Separate the names with a comma. For example, if you type Jo, all names that begin with Jo are displayed, i.e., Joe Smith, Joseph Flanders, Joanna Writh.

Note: When using the Domino Wizard, separate the list with a pipe '|'.

Click Advanced , to specify more detailed search (optional).
When the object names have been typed, click OK . The Source & 'Destination Mailboxes' dialog displays again with your selections listed in the box. Go to step 7.
Click Query Builder , to select groups of accounts to migrate.
In the Active Directory Query Builder dialog, click Browse to select the base distinguished name (DN) of the container to be used as the root for the search. If you want all folders under the selected DN base to be included in the migration, check Subtree.
To construct a filter to identify which mailboxes to import, click Create . A standard Window’s database query is displayed in the Filter box.
Click OK . The Source & Destination Mailboxes dialog refreshes with your selections listed in the box.

Note: The steps above are for the Exchange 6.0 Query Builder. If you are migrating from Exchange 5.5, the Query Builder dialog is different. You must enter the search base for the LDAP query and you must construct the filter to identify which mailboxes to import.

The Source & Destination Mailboxes dialog displays the Zimbra account name, the Exchange Store DN information and the Exchange server DN information. Review the information.
Click Remove , to remove accounts that should not be migrated.
Click Next , to continue.
The Wizard now checks to see if the accounts selected exists on the Zimbra server. After checking all the accounts, the Target Account 'Verification' dialog displays the number of accounts that exist and the number of accounts that do not exist on the Zimbra server. The accounts with the status of No such account will be created. Click Next.
The Account Provisioning dialog is displayed. All accounts with the status of No such account are shown in the Unprovisioned Accounts list box. Before creating these accounts, select the class of service that these accounts will be assigned. Classes of service that have been configured on the Zimbra server are listed. If you recently created a COS and it is not listed, click Refresh COS. Any new classes of service will be added to the list.

Note: If you do not want to create any of the accounts from this list, check Do not provision any users , and click Next. No accounts are created on the Zimbra server.

Click Next . The Provsioning Accounts dialog displays the progress and lists the accounts and their provisioning status.

At this point, the provisioning of email accounts on the Zimbra server is complete. Accounts are provisioned without passwords. You can either:

Create passwords for each account using either the administration console or the zmprov CLI utility.
Configure authentication to be external, against the LDAP directory and let the users continue to use their existing password.

Before proceeding you should change the mail relay information for these users to point to the Zimbra server instead of the Exchange server. Any new email messages are sent to the Zimbra mailboxes.

The Import Options dialog is used to set rules about what files should be imported

Note: By default, messages larger than 10 MB will not be imported. The message size includes the message and attachments. To change the default, see Preparing to Use the Migration Wizard.

The checkboxes for Import Junk-Mail Folder and Import Deleted Items 'Folde'r determine whether or not to import mail currently in those Outlook folders.
The checkbox for Ignore previously imported items can be used in cases where an earlier import operation was interrupted. If checked, the import process picks up where it left off, rather than to import duplicates.
Check the Date Filter checkbox to import mail only after a certain date. This lets you discard old messages.
In the Number of Mailboxes to import simultaneously: field, set the import concurrency level. Since the import is likely to happen while both Exchange and Zimbra servers continue to service other mail accounts, you should use caution when increasing this number, because setting this number too high may affect server performance.

Click Next . A confirmation dialog appears. Click OK to begin importing.

Important : Users can continue to work in Outlook while their mail is being imported, although any operation they do after that mailbox folder has been imported will not be picked up by the Zimbra server. To ensure that the imported mailbox is consistent with the old mailbox, we recommend informing users that their mailboxes will be unavailable over some scheduled downtime period.

The Import In Progress screen displays the import progress.

When the import is complete, the Import Completed dialog displays any errors. If errors or warnings appear, review the Description column and take appropriate action.
For more information, click Open Log File to view details.
Use Import More Users to re-run the import on a different batch of users. You might do this to import users from another domain, for example.

Setting Up Shared Domain with Exchange

You can set up a domain that is shared by Zimbra and Exchange with some users on the Exchange server, and other users on the Zimbra server. There are several potential ways to do this. The best way for your deployment depends on your site’s configuration, IT policies, and other conditions.
