Hello in our company we use gitlab-ce from 2018Q1. We want to upgrade it
to the latest quarterly.
The Problem ist we can't update from 2018Q1 to 2022Q1, gitlab-ce needs some
other major version upgrades.  For example We can jump from 2018Q1 ->
2018Q4 -> 2019Q2 .... 2022Q1.
Do you have any idea how to solve this problem? Or maybe old quarterly
packages are stored?
