+
+### Step 1. Permanently disable the **primary** cluster

+If the **primary** site goes offline, there may be data saved on the **primary** site
+that has not been replicated to the **secondary** site. This data should be treated
+as lost if you proceed.

+If an outage on the **primary** site happens, you should do everything possible to
+avoid a split-brain situation where writes can occur in two different GitLab
+instances, complicating recovery efforts. So to prepare for the failover, you
+must disable the **primary** site:

+ - Change DNS records (for example, point the primary DNS record to the
+ **secondary** site to stop usage of the **primary** site).
+ - Stop the virtual servers.
+ - Block traffic through a firewall.
+ - Revoke object storage permissions from the **primary** site.
+ - Physically disconnect a machine.

+
+1. Edit `/etc/gitlab/gitlab.rb` on the database node in the **secondary** site to
+ reflect its new status as **primary** by removing any lines that enabled the

+ ```
+
+ After making these changes, [reconfigure GitLab](../../restart_gitlab.md#omnibus-gitlab-reconfigure) on the database node.
+
+### Step 3. Promote the **secondary** cluster
+
+1. Find the task runner pod:
+
+ ```shell
+ kubectl --namespace gitlab get pods -lapp=task-runner
+ ```
+
+1. Promote the secondary:
+
+ ```shell
+ kubectl --namespace gitlab exec -ti gitlab-geo-task-runner-XXX -- gitlab-rake geo:set_secondary_as_primary
+ ```
+
+1. Update the existing cluster configuration.
+
+ You can retrieve the existing config with Helm:
+
+ ```shell
+ helm --namespace gitlab get values gitlab-geo > gitlab.yaml
+ ```
+
+ The existing config will contain a section for Geo that should resemble:
+
+ ```yaml
+ geo:
+ enabled: true
+ role: secondary
+ nodeName: secondary.example.com
+ psql:
+ host: geo-2.db.example.com
+ port: 5431
+ password:
+ secret: geo
+ key: geo-postgresql-password
+ ```
+
+ To promote the **secondary** cluster to a **primary** cluster, update `role: secondary` to `role: primary`.
+
+ You can remove the entire `psql` section if the cluster will remain as a primary site, this refers to the tracking database and will be ignored whilst the cluster is acting as a primary site.
+
+ Update the cluster with the new config:
+
+ ```shell
+ helm upgrade --install --version <current Chart version> gitlab-geo gitlab/gitlab --namespace gitlab -f gitlab.yaml
+ ```
+
+1. Verify you can connect to the newly promoted primary using the URL used previously for the secondary.
+
+1. Success! The secondary has now been promoted to primary.
