ZCS8 Upgrades Requiring OS Upgrades Also

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

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.
      • http://wiki.zimbra.com/wiki/Ports
  • 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.
