Updating GitLab installed with the Omnibus GitLab package

See the upgrade recommendations for suggestions on when to upgrade. If you are upgrading from a non-Omnibus installation to an Omnibus installation, check this guide.

Version specific changes

Updating to major versions might need some manual intervention. For more info, check the version your are updating to:

Mandatory upgrade paths for version upgrades

From version 10.8 onwards, upgrade paths are enforced for version upgrades by default. This restricts performing direct upgrades that skip major versions (for example 10.3 to 12.7 in one jump) which can result in breakage of the GitLab installations due to multiple reasons like deprecated or removed configuration settings, upgrade of internal tools and libraries etc. Users will have to follow the official upgrade recommendations while upgrading their GitLab instances.

Updating methods

There are two ways to update Omnibus GitLab:

Using the official repositories
Manually download the package

Both will automatically back up the GitLab database before installing a newer GitLab version. You may skip this automatic backup by creating an empty file at /etc/gitlab/skip-auto-backup:

sudo touch /etc/gitlab/skip-auto-backup

Note: For safety reasons, you should maintain an up-to-date backup on your own if you plan to use this flag.

Updating using the official repositories

If you have installed Omnibus GitLab Community Edition or Enterprise Edition, then the official GitLab repository should have already been set up for you.

To update to a newer GitLab version, all you have to do is:

# Debian/Ubuntu
sudo apt-get update
sudo apt-get install gitlab-ce

# Centos/RHEL
sudo yum install gitlab-ce

If you are an Enterprise Edition user, replace gitlab-ce with gitlab-ee in the above commands.

Updating using a manually downloaded package

If for some reason you don’t use the official repositories, it is possible to download the package and install it manually.

Visit the Community Edition repository or the Enterprise Edition repository depending on the edition you already have installed.
Find the package version you wish to install and click on it.
Click the ‘Download’ button in the upper right corner to download the package.
Once the GitLab package is downloaded, install it using the following commands, replacing XXX with the Omnibus GitLab version you downloaded:
```
# Debian/Ubuntu
dpkg -i gitlab-ce-XXX.deb

# CentOS/RHEL
rpm -Uvh gitlab-ce-XXX.rpm
```
If you are an Enterprise Edition user, replace gitlab-ce with gitlab-ee in the above commands.

Updating Community Edition to Enterprise Edition

To upgrade an existing GitLab Community Edition (CE) server, installed using the Omnibus packages, to GitLab Enterprise Edition (EE), all you have to do is install the EE package on top of CE. While upgrading from the same version of CE to EE is not explicitly necessary, and any standard upgrade jump (i.e. 8.0 to 8.7) should work, in the following steps we assume that you are upgrading the same versions.

The steps can be summed up to:

Find the currently installed GitLab version:
For Debian/Ubuntu
```
sudo apt-cache policy gitlab-ce | grep Installed
```
The output should be similar to: Installed: 8.6.7-ce.0. In that case, the equivalent Enterprise Edition version will be: 8.6.7-ee.0. Write this value down.
For CentOS/RHEL
```
sudo rpm -q gitlab-ce
```
The output should be similar to: gitlab-ce-8.6.7-ce.0.el7.x86_64. In that case, the equivalent Enterprise Edition version will be: gitlab-ee-8.6.7-ee.0.el7.x86_64. Write this value down.
Add the gitlab-ee Apt or Yum repository:
For Debian/Ubuntu
```
curl -s https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.deb.sh | sudo bash
```
For CentOS/RHEL
```
curl -s https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.rpm.sh | sudo bash
```
The above command will find your OS version and automatically set up the repository. If you are not comfortable installing the repository through a piped script, you can first check its contents.
Next, install the gitlab-ee package. Note that this will automatically uninstall the gitlab-ce package on your GitLab server. Reconfigure Omnibus right after the gitlab-ee package is installed. Make sure that you install the exact same GitLab version:
For Debian/Ubuntu
```
## Make sure the repositories are up-to-date
sudo apt-get update

## Install the package using the version you wrote down from step 1
sudo apt-get install gitlab-ee=8.6.7-ee.0

## Reconfigure GitLab
sudo gitlab-ctl reconfigure
```
For CentOS/RHEL
```
## Install the package using the version you wrote down from step 1
sudo yum install gitlab-ee-8.6.7-ee.0.el7.x86_64

## Reconfigure GitLab
sudo gitlab-ctl reconfigure
```
Note: If you want to upgrade to EE and at the same time also update GitLab to the latest version, you can omit the version check in the above commands. For Debian/Ubuntu that would be sudo apt-get install gitlab-ee and for CentOS/RHEL sudo yum install gitlab-ee.
Now go to the GitLab admin panel of your server (/admin/license/new) and upload your license file.
After you confirm that GitLab is working as expected, you may remove the old Community Edition repository:
For Debian/Ubuntu
```
sudo rm /etc/apt/sources.list.d/gitlab_gitlab-ce.list
```
For CentOS/RHEL
```
sudo rm /etc/yum.repos.d/gitlab_gitlab-ce.repo
```

That’s it! You can now use GitLab Enterprise Edition! To update to a newer version follow the section on Updating using the official repositories.

Note: If you want to use dpkg/rpm instead of apt-get/yum, go through the first step to find the current GitLab version and then follow the steps in Updating using a manually downloaded package.

Zero downtime updates

Note: This is only available in GitLab 9.1.0 or newer. Skipping restarts during reconfigure with /etc/gitlab/skip-auto-reconfigure was added in version 10.6. If running a version prior to 10.6, you will need to create /etc/gitlab/skip-auto-migrations.

It’s possible to upgrade to a newer version of GitLab without having to take your GitLab instance offline.

Verify that you can upgrade with no downtime by checking the Upgrading without downtime section of the update document.

If you meet all the requirements above, follow these instructions in order. There are three sets of steps, depending on your deployment type:

Deployment type	Description
Single	GitLab CE/EE on a single node
Multi-node / HA	GitLab CE/EE on multiple nodes
Geo	GitLab EE with Geo enabled
Multi-node / HA with Geo	GitLab CE/EE on multiple nodes

Single deployment

Create an empty file at /etc/gitlab/skip-auto-reconfigure. During software installation only, this will prevent the upgrade from running gitlab-ctl reconfigure and automatically running database migrations
```
sudo touch /etc/gitlab/skip-auto-reconfigure
```

Update the GitLab package

# Debian/Ubuntu
sudo apt-get update && sudo apt-get install gitlab-ce

# Centos/RHEL
sudo yum install gitlab-ce

If you are an Enterprise Edition user, replace gitlab-ce with gitlab-ee in the above command.

To get the regular migrations in place, run

sudo SKIP_POST_DEPLOYMENT_MIGRATIONS=true gitlab-ctl reconfigure

Once the node is updated and reconfigure finished successfully, complete the migrations with
```
sudo gitlab-rake db:migrate
```

Hot reload unicorn, puma and sidekiq services

sudo gitlab-ctl hup unicorn
sudo gitlab-ctl usr2 puma
sudo gitlab-ctl hup sidekiq

Note: If you do not want to run zero downtime upgrades in the future, make sure you remove /etc/gitlab/skip-auto-reconfigure after you’ve completed these steps.

Multi-node / HA deployment

Pick a node to be the Deploy Node. It can be any node, but it must be the same node throughout the process.

Deploy node

Create an empty file at /etc/gitlab/skip-auto-reconfigure. During software installation only, this will prevent the upgrade from running gitlab-ctl reconfigure and automatically running database migrations
```
sudo touch /etc/gitlab/skip-auto-reconfigure
```

All other nodes (not the Deploy node)

Ensure that gitlab_rails['auto_migrate'] = false is set in /etc/gitlab/gitlab.rb

Deploy node

Update the GitLab package

# Debian/Ubuntu
sudo apt-get update && sudo apt-get install gitlab-ce

# Centos/RHEL
sudo yum install gitlab-ce

If you are an Enterprise Edition user, replace gitlab-ce with gitlab-ee in the above command.

If you’re using PgBouncer:
You’ll need to bypass PgBouncer and connect directly to the database master before running migrations.
Rails uses an advisory lock when attempting to run a migration to prevent concurrent migrations from running on the same database. These locks are not shared across transactions, resulting in ActiveRecord::ConcurrentMigrationError and other issues when running database migrations using PgBouncer in transaction pooling mode.
To find the master node, run the following on a database node:
```
sudo gitlab-ctl repmgr cluster show
```
Then, in your gitlab.rb file on the deploy node, update gitlab_rails['db_host'] and gitlab_rails['db_port'] with the database master’s host and port.

To get the regular database migrations in place, run

sudo SKIP_POST_DEPLOYMENT_MIGRATIONS=true gitlab-ctl reconfigure

All other nodes (not the Deploy node)

Update the GitLab package
```
sudo apt-get update && sudo apt-get install gitlab-ce
```
If you are an Enterprise Edition user, replace gitlab-ce with gitlab-ee in the above command.
Ensure nodes are running the latest code
```
sudo gitlab-ctl reconfigure
```

Deploy node

Run post-deployment database migrations on deploy node to complete the migrations with
```
sudo gitlab-rake db:migrate
```

For nodes that run Unicorn or Sidekiq

Hot reload unicorn and sidekiq services

sudo gitlab-ctl hup unicorn
sudo gitlab-ctl hup sidekiq

If you’re using PgBouncer:
Change your gitlab.rb to point back to PgBouncer and run:
```
sudo gitlab-ctl reconfigure
```

For nodes that run Unicorn, Puma or Sidekiq

Hot reload unicorn, puma and sidekiq services

sudo gitlab-ctl hup unicorn
sudo gitlab-ctl usr2 puma
sudo gitlab-ctl hup sidekiq

Note: If you do not want to run zero downtime upgrades in the future, make sure you remove /etc/gitlab/skip-auto-reconfigure and revert setting gitlab_rails['auto_migrate'] = false in /etc/gitlab/gitlab.rb after you’ve completed these steps.

Geo deployment

Note: The order of steps is important. While following these steps, make sure you follow them in the right order, on the correct node.

Create an empty file at /etc/gitlab/skip-auto-reconfigure. During software installation only, this will prevent the upgrade from running gitlab-ctl reconfigure and automatically running database migrations
```
sudo touch /etc/gitlab/skip-auto-reconfigure
```

Update the GitLab package

# Debian/Ubuntu
sudo apt-get update && sudo apt-get install gitlab-ee

# Centos/RHEL
sudo yum install gitlab-ee

To get the database migrations in place, run

sudo SKIP_POST_DEPLOYMENT_MIGRATIONS=true gitlab-ctl reconfigure

Note: After this step you can get an outdated FDW remote schema on your secondary nodes. While it is not important to worry about at this point, you can check out the Geo troubleshooting documentation to resolve this.

Hot reload unicorn, puma and sidekiq services

sudo gitlab-ctl hup unicorn
sudo gitlab-ctl usr2 puma
sudo gitlab-ctl hup sidekiq

On each secondary node, executing the following:

Create an empty file at /etc/gitlab/skip-auto-reconfigure. During software installation only, this will prevent the upgrade from running gitlab-ctl reconfigure and automatically running database migrations
```
sudo touch /etc/gitlab/skip-auto-reconfigure
```

Update the GitLab package

# Debian/Ubuntu
sudo apt-get update && sudo apt-get install gitlab-ee

# Centos/RHEL
sudo yum install gitlab-ee

To get the database migrations in place, run

sudo SKIP_POST_DEPLOYMENT_MIGRATIONS=true gitlab-ctl reconfigure

Hot reload unicorn, puma, sidekiq and restart geo-logcursor services

sudo gitlab-ctl hup unicorn
sudo gitlab-ctl usr2 puma
sudo gitlab-ctl hup sidekiq
sudo gitlab-ctl restart geo-logcursor

Run post-deployment database migrations, specific to the Geo database
```
sudo gitlab-rake geo:db:migrate
```

After all secondary nodes are updated, finalize the update on the primary node:

Run post-deployment database migrations
```
 sudo gitlab-rake db:migrate
```

On each secondary, ensure the FDW tables are up-to-date.

Wait for the primary migrations to finish.
Wait for the primary migrations to replicate. You can find “Data replication lag” for each node listed on Admin Area > Geo.
Refresh Foreign Data Wrapper tables
```
sudo gitlab-ctl reconfigure
```

After updating all nodes (both primary and all secondaries), check their status:

Verify Geo configuration and dependencies
```
 sudo gitlab-rake gitlab:geo:check
```

Multi-node / HA deployment with Geo

This section describes the steps required to upgrade a multi-node / HA deployment with Geo. Some steps must be performed on a particular node. This node will be known as the “deploy node” and is noted through the following instructions.

You now need to nominate:

One instance for use as the primary “deploy node”.
A second instance for use as the secondary “deploy node”.

Updates must be performed in the following order:

Update Geo primary multi-node deployment.
Update Geo secondary multi-node deployment.
Post-deployment migrations and checks.

Step 1: Updating the Geo primary multi-node deployment

On all nodes including primary and secondary “deploy nodes”

Create an empty file at /etc/gitlab/skip-auto-reconfigure. During software installation only, this will prevent the upgrade from running gitlab-ctl reconfigure and automatically running database migrations.

sudo touch /etc/gitlab/skip-auto-reconfigure

On all other nodes excluding the primary “deploy node”

Ensure that gitlab_rails['auto_migrate'] = false is set in /etc/gitlab/gitlab.rb.
Ensure nodes are running the latest code
```
sudo gitlab-ctl reconfigure
```

On the primary “deploy node”

Update the GitLab package

# Debian/Ubuntu
sudo apt-get update && sudo apt-get install gitlab-ee

# Centos/RHEL
sudo yum install gitlab-ee

To get the regular database migrations in place, run

sudo SKIP_POST_DEPLOYMENT_MIGRATIONS=true gitlab-ctl reconfigure

On all other nodes excluding the primary “deploy node”

Update the GitLab package

# Debian/Ubuntu
sudo apt-get update && sudo apt-get install gitlab-ee

# Centos/RHEL
sudo yum install gitlab-ee

Ensure nodes are running the latest code
```
sudo gitlab-ctl reconfigure
```

For all nodes that run Unicorn or Sidekiq

Hot reload unicorn and sidekiq services:

sudo gitlab-ctl hup unicorn
sudo gitlab-ctl hup sidekiq

Step 2: Updating each Geo secondary multi-node deployment

Note: Only proceed if you have successfully completed all steps on the primary “deploy node”.

On all nodes including primary and secondary “deploy nodes”

sudo touch /etc/gitlab/skip-auto-reconfigure

On all other nodes excluding the primary “deploy node”

Ensure that geo_secondary['auto_migrate'] = false is set in /etc/gitlab/gitlab.rb
Ensure nodes are running the latest code
```
sudo gitlab-ctl reconfigure
```

On the secondary “deploy node”

Update the GitLab package

# Debian/Ubuntu
sudo apt-get update && sudo apt-get install gitlab-ee

# Centos/RHEL
sudo yum install gitlab-ee

To get the regular database migrations in place, run

sudo SKIP_POST_DEPLOYMENT_MIGRATIONS=true gitlab-ctl reconfigure

On all nodes excluding the primary “deploy node”

Update the GitLab package

# Debian/Ubuntu
sudo apt-get update && sudo apt-get install gitlab-ee

# Centos/RHEL
sudo yum install gitlab-ee

Ensure nodes are running the latest code
```
sudo gitlab-ctl reconfigure
```

For all nodes that run Unicorn, Sidekiq, or the geo-logcursor daemon

Hot reload unicorn, sidekiq and geo-logcursor services:

sudo gitlab-ctl hup unicorn
sudo gitlab-ctl hup sidekiq
sudo gitlab-ctl restart geo-logcursor

Step 3: Run post-deployment migrations and checks

On the primary “deploy node”

Run post-deployment database migrations:
```
sudo gitlab-rake db:migrate
```
Verify Geo configuration and dependencies
```
sudo gitlab-rake gitlab:geo:check
```

On all nodes excluding the primary “deploy node”

Run post-deployment database migrations, specific to the Geo database:
```
sudo gitlab-rake geo:db:migrate
```
Wait for the primary migrations to finish.
Wait for the primary migrations to replicate. You can find “Data replication lag” for each node listed on Admin Area > Geo. These wait steps help ensure the FDW tables are up-to-date.
Refresh Foreign Data Wrapper tables
```
sudo gitlab-ctl reconfigure
```
Verify Geo configuration and dependencies
```
sudo gitlab-rake gitlab:geo:check
```
Verify Geo status
```
sudo gitlab-rake geo:status
```

Upgrading Gitaly servers

Gitaly servers must be upgraded to the newer version prior to upgrading the application server. This prevents the GRPC client on the application server from sending RPCs that the old Gitaly version does not support.

Downgrading

This section contains general information on how to revert to an earlier version of a package.

Note: This guide assumes that you have a backup archive created under the version you are reverting to.

These steps consist of:

Download the package of a target version.(example below uses GitLab 6.x.x)
Stop GitLab
Install the old package
Reconfigure GitLab
Restoring the backup
Starting GitLab

See example below:

First download a GitLab 6.x.x CE or EE (subscribers only) package.

Steps:

Stop GitLab:

sudo gitlab-ctl stop unicorn
sudo gitlab-ctl stop sidekiq

Downgrade GitLab to 6.x:

# Ubuntu
sudo dpkg -r gitlab
sudo dpkg -i gitlab-6.x.x-yyy.deb

# CentOS:
sudo rpm -e gitlab
sudo rpm -ivh gitlab-6.x.x-yyy.rpm

Prepare GitLab for receiving the backup restore. Due to a backup restore bug in versions earlier than GitLab 6.8.0, it is needed to drop the database before running gitlab-ctl reconfigure, only if you are downgrading to 6.7.x or less:
```
sudo -u gitlab-psql /opt/gitlab/embedded/bin/dropdb gitlabhq_production
```
Reconfigure GitLab (includes database migrations):
```
sudo gitlab-ctl reconfigure
```

Restore your backup:

 sudo gitlab-backup restore BACKUP=12345 # where 12345 is your backup timestamp

Start GitLab:
```
sudo gitlab-ctl start
```

Updating GitLab CI from prior `5.4.0` to version `7.14` via Omnibus GitLab

Warning: Omnibus GitLab 7.14 was the last version where CI was bundled in the package. Starting from GitLab 8.0, CI was merged into GitLab, thus it’s no longer a separate application included in the Omnibus package.

In GitLab CI 5.4.0 we changed the way GitLab CI authorizes with GitLab.

In order to use GitLab CI 5.4.x, GitLab 7.7.x is required.

Make sure that GitLab 7.7.x is installed and running and then go to Admin section of GitLab. Under Applications create a new a application which will generate the app_id and app_secret.

In /etc/gitlab/gitlab.rb:

gitlab_ci['gitlab_server'] = { "url" => 'http://gitlab.example.com', "app_id" => '12345678', "app_secret" => 'QWERTY12345' }

Where url is the url to the GitLab instance.

Make sure to run sudo gitlab-ctl reconfigure after saving the configuration.

RPM ‘package is already installed’ error

If you are using RPM and you are upgrading from GitLab Community Edition to GitLab Enterprise Edition you may get an error like this:

package gitlab-7.5.2_omnibus.5.2.1.ci-1.el7.x86_64 (which is newer than gitlab-7.5.2_ee.omnibus.5.2.1.ci-1.el7.x86_64) is already installed

You can override this version check with the --oldpackage option:

sudo rpm -Uvh --oldpackage gitlab-7.5.2_ee.omnibus.5.2.1.ci-1.el7.x86_64.rpm

Package obsoleted by installed package

CE and EE packages are marked as obsoleting and replacing each other so that both aren’t installed and running at the same time.

If you are using local RPM files to switch from CE to EE or vice versa, use rpm for installing the package rather than yum. If you try to use yum, then you may get an error like this:

Cannot install package gitlab-ee-11.8.3-ee.0.el6.x86_64. It is obsoleted by installed package gitlab-ce-11.8.3-ce.0.el6.x86_64

To avoid this issue, either:

Use the same instructions provided in the Updating using a manually downloaded package section.
Temporarily disable obsoletion checking in yum by adding --setopt=obsoletes=0 to the options given to the command.
