Upgrade from 8.8.9 GA to 8.8.11 GA Community

[ivanv]

Hi,

current version of Zimbra is Release 8.8.9_GA_2055.RHEL7_64_20180703080917 RHEL7_64 FOSS edition, Patch 8.8.9_P1
on Centos 7.5.1804.

I would like to update to latest version of Zimbra 8.8.11 GA Patch 2 . Can I perform update directly to 8.8.11 from 8.8.9 or do I need to update to 8.8.10 first?

How do I perform update? Do I download specific version and run install.sh?

Thanks,
Ivan

This has been answered many times in the forums and even in the Release Notes (if anyone reads them). Just download the most recent version of ZCS and run the installer but do make sure that you read the release notes (in detail) to see if anything in the upgrade might affect your current installation.

Hi,

thank you for answer.

I read release notes and requirements in detail but couldn't find any information about upgrade from non-last version.

I would do comprehensive backup before upgrade.
