ZCS8 Upgrades Requiring OS Upgrades Also

ZCS6 On RHEL5 TO ZCS8 or ZCS7 on RHEL6

Redhat is not supporting upgrades from RHEL5 to RHEL6. The option is available, but they state they do not support it.

https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/ch-upgrade-x86.html

You will need to decide if you will or will not do the in-place upgrade or not.

If you do, I would recommend the following:

  • Download all ZCS installer packages you'll need. [Download ZCS7 for RHEL5, ZCS7 for RHEL6, and ZCS8 for RHEL6]
  • 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.
  • Upgrade to ZCS7 on RHEL5
    • Disable the zimbra services from starting on reboot/start.
  • Perform the RHEL6 upgrade
  • Then install ZCS7 for REHL6.
  • Confirm operations. Decide if you want to now proceed with the upgrade to ZCS8, upgrade to ZCS8 for RHEL6 if so.
  • Confirm operations and re-enable the init startup for zimbra.
  • Remove network access blocks.

If you want to bypass the one upgrade, you would:

  • Download all ZCS installer packages you'll need. [Download ZCS8 for RHEL6]
  • 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.
  • Upgrade your server from RHEL5 to RHEL6.
  • Then install the ZCS8 installer for RHEL6.
  • Confirm operations and re-enable the init startup for zimbra.
  • Remove network access blocks.

If you are planning on using a new server, then I would need to know your disk infrastructure to see what the best course would be.

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.
