Patch Installation

8.8.8 Patch Change: Please read!

**This note is applicable only if you are upgrading from 8.8.8 GA or 8.8.8 Patch1 to latest patch. Ignore, if you are upgrading from 8.8.8 Patch2 or higher version of 8.8.8 Patch.

8.8.8 Patch (zimbra-patch) checks if your system is Network Edition and if so adds a new Network Edition-only package repository. As a result, after 8.8.8 Patch installation is completed, Network edition customers will need to run another package update/upgrade process to obtain the updated Network Edition only packages available from newly added package repository.

Before Installing the Patch

Before installing the patch, consider the following:

  • Patches are cumulative.
  • A full backup should be performed before any patch is applied. There is no automated roll-back.
  • Zimlet patches can include removing existing Zimlets and redeploying the patched Zimlet.
  • Only files or Zimlets associated with installed packages will be installed from the patch.
  • Switch to user zimbra before using ZCS CLI commands.
  • Important! You cannot revert to the previous ZCS release after you upgrade to the patch.
  • Important Note for ZCS Setup with Local ZCS repository: Customers who have setup local ZCS repository should first update the local repository by following instructions in wiki

Install the Patch

Note: This patch should be installed only on all mailbox nodes running in your environment.

With 8.8.8 Patches, customers would not need to download any ZCS Patch builds. Patch packages can be installed by using Linux package management commands.

  • Please make note that, installing zimbra-patch package only updates the Zimbra core packages. administrator would need to upgrade other applicable packages like zimbra-chat, zimbra-network-modules-ng, zimbra-talk.
  • Note regarding Chat and Talk package conflict
    • zimbra-chat and zimbra-talk packages conflict each other.
    • Ubuntu will ask user's confirmation before removing already installed package and installing the conflicting package.
    • Redhat will give error if conflict found and user will have to remove installed package before installing conflicting package.
