Updating your cluster version

To update your Data Center Edition to a newer version:

1. Determine the update path.
2. Read the upgrade notes between the SonarQube Server versions.
3. Back up the SonarQube Server database.
4. Stop the cluster.
5. Update each application and search node as follows (do not trigger the setup phase):
   • Perform the pre-update steps.
   • Perform the update.
   • Perform the post-update steps.
6. Once all nodes have the same binaries: restart the cluster.
7. At this point, only one of the application nodes is up and waiting for the /setup endpoint to be accessed. Try to access node_ip:port/setup on each application node, and trigger the setup operation on the one that responds.
