Good afternoon,

I have recently been tasked with upgrading OTRS from a rather old version (3.1.11) to the latest version.

I have access to the old server, plus I have stood up a brand new CentOS VM for the new installation.

I cannot find any information online about performing such a large upgrade, and wondered whether anyone here could point me to a resource (or if not, could provide assistance).

Thank you very much.

Pete
