I can't get over how easy it is with the Omnibus distribution. They obviously take great care in making sure it works. I keep ours up to date, so upgrades tend to be easy, but even going to new major releases (11->12, 12->13, etc.) have been just a "yum update" away and it all just works.

They've done this for quite a while too. When I took over managing our Gitlab instance it was 3 major versions behind. I just went back and followed their directions to get to certain minimal levels, then could do a major version update. Then do another incremental to another specific level, then do it again. It took a little while, but it worked perfectly.

I really appreciate the time and effort they put into making sure that the upgrade process is smooth.
