GitLab upgrade paths

Upgrading or installing GitLab can be a very simple or very complicated endeavor, depending on how you perform it and what are your requirements.

In my setup, I had GitLab version 12.6.3-ee.0 installed using Omnibus on an Ubuntu 18.04. At the moment, the latest version of GitLab is 13.3, but I chose to upgrade to the latest version of 13.2.x, as I considered it more stable. I will upgrade to 13.3.x when 13.4.x appears.

These are the raw information I used when choosing the upgrade path:

I chose to perform the upgrade in multiple stages, 7 to be more exact:

  • 12.6.3 -> 12.6.8 -> 12.7.9 -> 12.8.10 -> 12.9.10 -> 12.10.14 -> 13.0.14 ->13.2.9

I have chosen the path as I wanted to perform upgrades between minor version to minor version. In addition, upgrade 12.6.3 -> 12.6.8 was added for a safer patch to patch version upgrade (according to semantic versioning MAJOR.MINOR.PATCH).

Besides the apt upgrade, two manual interventions were required:

  • update unicorn settings when upgrading from 12.6.3-ee.0 to 12.6.8-ee.0
  • upgrade Postgres version to v11 after installing GitLab version 12.8.10-ee.0

The following script should not be run automatically, as things can go wrong with every upgrade. Perform functional tests between every upgrade to make sure GitLab works as expected.

And voila! My gitlab setup is live and happy:

The commands should be run with administrative privileges (sudo):


# perform an apt update
apt update

# check the installed gitlab version
dpkg --list | grep -i gitlab

# check the available gitlab versions
apt-cache policy gitlab-ee

# get gitlab env information
gitlab-rake gitlab:env:info

# after every upgrade run the reconfigure / restart
# to make sure nothing is broken before the next upgrade
function check_restart_gitlab {
    gitlab-ctl reconfigure
    gitlab-ctl restart

# perform upgrade from 12.6.3-ee.0 to 12.6.8-ee.0
apt install gitlab-ee=12.6.8-ee.0
# manual step
# set in gitlab.rc:
#    unicorn['worker_memory_limit_min'] = "1024 * 1 << 20"
#    unicorn['worker_memory_limit_max'] = "1280 * 1 << 20"

# perform upgrade from 12.6.8-ee.0 to 12.7.9-ee.0
apt install gitlab-ee=12.7.9-ee.0

apt install gitlab-ee=12.8.10-ee.0
# perform upgrade from 12.7.9-ee.0 to 12.8.10-ee.0
apt install gitlab-ee=12.8.10-ee.0

# upgrade postgres to version 11
gitlab-ctl pg-upgrade
gitlab-ctl pg-upgrade -V 11

# perform upgrade from 12.8.10-ee.0 to 12.9.10-ee.0
apt install gitlab-ee=12.9.10-ee.0

# perform upgrade from 12.9.10-ee.0 to 12.10.14-ee.0
apt install gitlab-ee=12.10.14-ee.0

# perform upgrade from 12.10.14-ee.0 to 13.0.14-ee.0
apt install gitlab-ee=13.0.14-ee.0

# perform upgrade from 13.0.14-ee.0 to 13.2.9-ee.0
apt install gitlab-ee=13.2.9-ee.0
