ZCS8 Upgrades Requiring OS Upgrades Also

Reference: https://www.zimbra.com/downloads/ne-downloads.html

RHEL

Ubuntu

ZCS 8 is available for Ubuntu 12.04 LTS , but Ubuntu 12.04 LTS is not available/supported for ZCS7x . You will have to schedule and do the upgrade to both during the same downtime window.

  • Download all ZCS installer packages you'll need. [Download zimbra 8 installer for Ubuntu 12.04]
  • Read the Release Notes - the actual upgrade process is detailed in there for ZCS.
  • Make sure you have a proper backup.
  • During schedule downtime:
    • Block client/mail type network access to server.
      • You'll need access to our license server [license.zimbra.com] .
      • If you have multiple ZCS servers, they'll need network access to each other.
    • Disable the zimbra services from starting on reboot/start.
  • Do OS upgrade. [Ubuntu 12.04 LTS]
  • Do Zimbra upgrade. [ZCS8 for Ubuntu 12.04 LTS]
  • Confirm operations and re-enable the init startup for zimbra.
  • Remove network access blocks.

The above is for a single server install and where the option of using another server for the transition isn't an option.
