The Gitlab documentation at Upgrading GitLab | GitLab reads as follows -
Upgrading without downtime
Starting with GitLab 9.1.0 it’s possible to upgrade to a newer major, minor, or patch version of GitLab without having to take your GitLab instance offline. However, for this to work there are the following requirements: You can only upgrade 1 minor release at a time. So from 9.1 to 9.2, not to 9.3.
It it still necessary to carry-out all minor within-version upgrades on versions 12 and 13 please?
For example, to upgrade from 12.1 to 12.10, is it still the case that I require to upgrade from 12.1 to 12.2 to 12.3 to 12.4 to 12.5 to 12.6 to 12.7 to 12.8 to 12.9 to 12.10 please?
