Ubuntu Upgrades
Ubuntu Upgrades
For current ZCS versions (8.8.15+) and Ubuntu versions (18.04+) please check this page: https://wiki.zimbra.com/wiki/AGibanelBtactic-Ubuntu-Upgrade
Upgrade Ubuntu 10.04 64bit to Ubuntu 12.04 64bit and update ZCS 8.0.8
Stopping the Zimbra Collaboration Services
The first step in this Upgrade guide is stop our Zimbra Collaboration Services:
zimbra@help:/home/# su - zimbra -c 'zmcontrol stop'
Once we have stopped the Zimbra Collaboration services and we have a full Backup or Snapshot, we can continue.
Upgrading the Ubuntu Version
In Ubuntu 10, we need to install the update-manager-core if isn´t installed.
root@zimbralab03:/# sudo apt-get install update-manager-core
Next we need to be sure that in the update manager are only selected LTS versions, check the next file, and the prompt line must be prompt=lts
root@zimbralab03:/# sudo vi /etc/update-manager/release-upgrades
Update all the packages and dependencies before do a upgrade with the next command
root@zimbralab03:/# sudo apt-get update && sudo apt-get upgrade && sudo apt-get autoremove
Now is time for start the Upgrade proces with the next command
root@zimbralab03:/# sudo do-release-upgrade
In case of this command fails somehow, please use the next command to start the upgrade
sudo apt-get update && sudo apt-get upgrade
The process will start and do some previous questions, for example about create an alternate SSH daemon, just in case if we lose the actual SSH connection:
Continue running under SSH? This session appears to be running under ssh. It is not recommended to perform a upgrade over ssh currently because in case of failure it is harder to recover. If you continue, an additional ssh daemon will be started at port '1022'. Do you want to continue? Continue [yN] y Starting additional sshd To make recovery in case of failure easier, an additional sshd will be started on port '1022'. If anything goes wrong with the running ssh you can still connect to the additional one. To continue please press [ENTER]
After a while checking packages, the wizard will ask about the total MB to download and will require our answer, in this case we will write Y and press ENTER:
Do you want to start the upgrade? 5 packages are going to be removed. 69 new packages are going to be installed. 234 packages are going to be upgraded. You have to download a total of 158 M. This download will take about 1 minute with your connection. Installing the upgrade can take several hours. Once the download has finished, the process cannot be canceled. Continue [yN] Details [d]y
During the proccess, have questions like this or others, we need to take careful and select the default answer, so only need to press ENTER all time:
Configuration file `/etc/sysctl.conf'
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
*** sysctl.conf (Y/I/N/O/D/Z) [default=N] ?
During the proccess will have questions prompt about delete packages, again select the default option:
Remove obsolete packages? 18 packages are going to be removed. Continue [yN] Details [d]y
And after a while, the final and good message, reboot time: System upgrade is complete.
Restart required To finish the upgrade, a restart is required. If you select 'y' the system will be restarted. Continue [yN] y

Upgrade Zimbra Collaboration 8.0.7 to 8.5.0 - Ubuntu 12.04
Verifying the expiration date of the SSL Certificate
Zimbra Collaboration requires always, at least, a Self-Signed SSL Certificate for do the communication between the different components. The Self-Signed SSL certificate is auto-deployed once we install Zimbra Collaboration.
Is highly recommend check the SSL Certificate expiration's date, with the next command:
/opt/zimbra/bin/zmcertmgr viewdeployedcrt
If the date is near to expires, is extremely recommended re-generate the Self-Signed SSL Certificate before do the Upgrade:
root@help:/opt/zimbra/ssl/zimbra# /opt/zimbra/bin/zmcertmgr createca -new root@help:/opt/zimbra/ssl/zimbra# /opt/zimbra/bin/zmcertmgr createcrt -new -days 365 root@help:/opt/zimbra/ssl/zimbra# /opt/zimbra/bin/zmcertmgr deploycrt self
Upgrade Instructions
The first thing that need to to, is download the proper Zimbra Collaboration Version, in this case for Ubuntu 12.04 LTS:

Upgrade complete.
In the end of the Installation, the wizard will ask us about Notify Zimbra, is always appreciated and good idea if we can do it.
You have the option of notifying Zimbra of your installation.
This helps us to track the uptake of the Zimbra Collaboration Server.
The only information that will be transmitted is:
The VERSION of zcs installed (8.5.0_GA_3040_UBUNTU12_64)
The ADMIN EMAIL ADDRESS created (admin@YYYYYIIII.es)
Notify Zimbra of your installation? [Yes] yes
The last message is the pat to the Log file if we can check or save our process:
Moving /tmp/zmsetup08262014-185850.log to /opt/zimbra/log
Configuration complete – press return to exit
Upgrade Ubuntu 12.04 to Ubuntu 14.04 and update ZCS 8.5.0
Template:Note Is very important before continue with this process, take a Snapshot or do a Full Backup of your System.
Stopping the Zimbra Collaboration Services
The first step in this Upgrade guide is stop our Zimbra Collaboration Services:
zimbra@help:/home/# su - zimbra -c 'zmcontrol stop'
Once we have stopped the Zimbra Collaboration services and we have a full Backup or Snapshot, we can continue.
Upgrading the Ubuntu Version
For Upgrade the Ubuntu version, in root session we will execute this command:
root@help:/home/# do-release-upgrade
This process will start and do some previous questions, for example it will ask us about create an alternate SSH daemon, just in case if we lose the actual SSH connection:
Continue running under SSH?
This session appears to be running under ssh. It is not recommended
to perform a upgrade over ssh currently because in case of failure it
is harder to recover.
If you continue, an additional ssh daemon will be started at port
‘1022’.
Do you want to continue?
Continue [yN] y
Starting additional sshd
To make recovery in case of failure easier, an additional sshd will
be started on port ‘1022’. If anything goes wrong with the running
ssh you can still connect to the additional one.
If you run a firewall, you may need to temporarily open this port. As
this is potentially dangerous it’s not done automatically. You can
open the port with e.g.:
‘iptables -I INPUT -p tcp –dport 1022 -j ACCEPT’
To continue please press [ENTER]
After a while checking packages, the wizard will ask about the total MB to download and will require our answer, in this case we will write Y and press ENTER:
Do you want to start the upgrade?
2 packages are going to be removed. 113 new packages are going to be
installed. 380 packages are going to be upgraded.
You have to download a total of 216 M. This download will take about
5 minutes with your connection.
Installing the upgrade can take several hours. Once the download has
finished, the process cannot be canceled.
Continue [yN] Details [d]y
The Wizard will ask us during the process some questions with Yes or No for answer it, we will let the default Answer:

==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer’s version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
*** limits.conf (Y/I/N/O/D/Z) [default=N] ?
Also, we will have questions prompt us about delete packages, again we will select the default answer:
Remove obsolete packages?
22 packages are going to be removed.
Continue [yN] Details [d]
And after a while, the final and good message, reboot time:
System upgrade is complete.
Restart required
To finish the upgrade, a restart is required.
If you select ‘y’ the system will be restarted.
Continue [yN] y
Once we do a reboot, we will have Ubuntu 14.04 LTS running in our System:
Distributor ID: Ubuntu

Now as usual it will ask to install packages, say Y to the packages you had before release upgrade The system will start to update, we can see all the progress in interactive way.
Now copy "install_history" and "localconfig.xml" files from the backup location which we took, without this step do not start ZCS upgrade step else installer will behave like a fresh installation.
cp -pvr /opt/zimbra_backup/zimbra/.install_history /opt/zimbra/.install_history cp -pvr /opt/zimbra/zimbra_backup/conf/localconfig.xml /opt/zimbra/conf/localconfig.xml
Run "/opt/zimbra/libexec/zmsetup.pl" to complete configuration part, this step will take only few minutes to complete configuration.
And now we will have Zimbra 8.7 or above and Ubuntu 16 working together.
Upgrade Ubuntu 16.x to Ubuntu 18.x and update ZCS 8.8.15 & above
Template:Note Is very important before continue with this process, take a Snapshot or do a Full Backup of your System.
Stopping the Zimbra Collaboration Services
The first step in this Upgrade guide is stop our Zimbra Collaboration Services:
zimbra@help:/home/# su - zimbra -c 'zmcontrol stop'
Backup configuration files, installed zimbra package list and ldap
Take backup of .install_history and localconfig.xml file
mkdir -p /opt/{zimbra_backup/.saveconfig,ldap_backup}
chown zimbra:zimbra /opt/{zimbra_backup,ldap_backup} -R
cp -pvr /opt/zimbra/.install_history /opt/zimbra_backup/.saveconfig/.install_history
cp -pvr /opt/zimbra/conf/localconfig.xml /opt/zimbra_backup/.saveconfig/localconfig.xml
Backup installed zimbra package list
apt list --installed | grep -i 'zimbra-' | cut -d'/' -f1 > /opt/zimbra_backup/.saveconfig/.installedPackages
Backup ldap
su - zimbra
/opt/zimbra/libexec/zmslapcat -c /opt/ldap_backup/
/opt/zimbra/libexec/zmslapcat -a /opt/ldap_backup/
/opt/zimbra/libexec/zmslapcat /opt/ldap_backup/
Install sysv-rc-conf to check and enable/disable zimbra service at boot time
apt-get install sysv-rc-conf
sysv-rc-conf zimbra off
sysv-rc-conf --list zimbra
zimbra 0:off 1:off 2:off 5:off 6:off
Upgrading the Ubuntu packages and Release Version
apt-get update && apt-get dist-upgrade init 6
Edit "/etc/update-manager/release-upgrades" using your favorite editor and set "Prompt=lts"
For Upgrade the Ubuntu version, in root session we will execute this command:
do-release-upgrade
This process will start and do some previous questions, for example it will ask us about create an alternate SSH daemon, just in case if we lose the actual SSH connection:
Reading cache Checking package manager Continue running under SSH? This session appears to be running under ssh. It is not recommended to perform a upgrade over ssh currently because in case of failure it is harder to recover. If you continue, an additional ssh daemon will be started at port '1022'. Do you want to continue? Continue [yN] y Starting additional sshd To make recovery in case of failure easier, an additional sshd will be started on port '1022'. If anything goes wrong with the running ssh you can still connect to the additional one. If you run a firewall, you may need to temporarily open this port. As this is potentially dangerous it's not done automatically. You can open the port with e.g.: 'iptables -I INPUT -p tcp --dport 1022 -j ACCEPT' To continue please press [ENTER]
After a while checking packages, the wizard will ask about the total MB to download and will require our answer, in this case we will write Y and press ENTER:
Do you want to start the upgrade? 14 installed packages are no longer supported by Canonical. You can still get support from the community. 101 packages are going to be removed. 147 new packages are going to be installed. 405 packages are going to be upgraded. You have to download a total of 264 M. This download will take about 1 minute with your connection. Installing the upgrade can take several hours. Once the download has finished, the process cannot be canceled. Continue [yN] Details [d]
We will have questions like this, we need to take careful and select the default answer, so we only need to press ENTER all time:
Configuration file `/etc/security/limits.conf’
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer’s version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
*** limits.conf (Y/I/N/O/D/Z) [default=N] ?
Also, we will have questions prompt us about delete packages, again we will select the default answer:
Remove obsolete packages?
22 packages are going to be removed.
Continue [yN] Details [d]
And after a while, the final and good message, reboot time:
System upgrade is complete.
Restart required
To finish the upgrade, a restart is required.
If you select ‘y’ the system will be restarted.
Continue [yN] y
Once we do a reboot, we will have Ubuntu 18.04 LTS running in our System:
Distributor ID: Ubuntu
Description: Ubuntu 18.04.3 LTS
Release: 18.04
Codename: trusty
Update Zimbra 8.8.15 and above with Ubuntu 16.x package
The first step is download and extract the correct version for our new OS, Ubuntu 18.x LTS:
[11]Open Source Edition Download [12]Network Edition Download
Now, we are ready to launch the install.sh script:
./install.sh -s --skip-activation-check
**Remember that if it ask to delete /opt/zimbra directory say No
Configuring package repository Checking for installable packages Found zimbra-core (local) Found zimbra-ldap (local) Found zimbra-logger (local) Found zimbra-mta (local) Found zimbra-dnscache (local) Found zimbra-snmp (local) Found zimbra-store (local) Found zimbra-apache (local) Found zimbra-spell (local) Found zimbra-convertd (local) Found zimbra-memcached (repo) Found zimbra-proxy (local) Found zimbra-archiving (local) Found zimbra-drive (repo) Found zimbra-imapd (local) Found zimbra-patch (repo) Found zimbra-mta-patch (repo) Found zimbra-proxy-patch (repo) Found zimbra-license-tools (local) Found zimbra-license-extension (local) Found zimbra-network-store (local) Found zimbra-network-modules-ng (local) The Zimbra Collaboration Server does not appear to be installed, yet there appears to be a ZCS directory structure in /opt/zimbra.

Now as usual it will ask to install packages, say Y to the packages you had before release upgrade The system will start to update, we can see all the progress in interactive way.
Depending on specific Ubuntu package, the above step would cause the Zimbra packages to be removed because the dependency is being removed (= upgraded). Manually upgrading with apt-get (dist-)upgrade leaves the Zimbra apt repository in place, and will pull in the correct Zimbra packages for the new Ubuntu version automatically.
apt update apt upgrade
Now copy "install_history" and "localconfig.xml" files from the backup location which we took, without this step do not start ZCS upgrade step else installer will behave like a fresh installation.
cp -pvr /opt/zimbra_backup/.saveconfig/.install_history /opt/zimbra/.install_history cp -pvr /opt/zimbra_backup/.saveconfig/localconfig.xml /opt/zimbra/conf/localconfig.xml
Run "/opt/zimbra/libexec/zmsetup.pl" to complete configuration part, this step will take only few minutes to complete configuration.
And now we will have Zimbra 8.8.15 or above and Ubuntu 18 working together.
Special Notes about Licensing
License Activation is required when upgrading to ZCS 7 or later.
The ZCS Network upgrade will automatically attempt to activate the current license as long as the activation server can be contacted.
You can obtain a manual activation key and re-run the upgrade by specifying the -a activation.xml option.
A manual license activation key can be obtained by either visiting the Zimbra support portal or contacting Zimbra support or sales.
