Patch Installation

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.

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. Customers who have setup local ZCS repository should first update the local repository by following instructions in wiki

  • 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.
  • Also, please note that, updating zimbra-talk package would remove existing zimbra-chat package and upgrade zimbra-network-modules-ng to the latest version. So, if you plan to update zimbra-talk package, then updating zimbra-network-modules-ng step can be skipped.
