We have a gitlab-ce 9.1.2-ce.0 installation on Debian Jessie, installed using the official Debian packages:
apt-get install gitlab-ce
apt-get update apt-get install gitlab-ce
we wish to upgrade to 11.4.5-ce.0 (the most current version in the official Debian repository).
"From version 10.8 onwards, upgrade paths are enforced for version upgrades by default. This restricts performing direct upgrades that skip major versions [..] which can result in breakage [...]"
I assume this would apply in our case.
What is the official way to enforce the required upgrade path?
Needless to say, we want to rule out or at least minimize breakage.
During the upgrade, the GitLab installation will be taken off line entirely. Therefore, downtime is not an issue in this case.
Thank you kindly in advance.
