Upgrade steps are confusing in documentation, and don’t work. Omnibus chef cookbooks seem to overwrite manual changes to mattermost install directory
Steps to reproduce
Gitlab 11.4.6 Mattermost 5.3.1
Follow upgrade instructions https://docs.mattermost.com/administration/upgrade.html
Mattermost is upgraded to 5.5 after above steps
Mattermost remains at version 5.3.1
Is there an easier omnibus mechanism to upgrade mattermost? or is there expectations that a near future release of omnibus gitlab will include mattermost 5.5? 5.3.1 currently is not importing slack data and we need this feature asap.
