Use the following information to upgrade your Keycloak version.
CAUTION:
- Upgrading Keycloak requires downtime and should be performed in a test environment before being attempted in a production environment.
- After the upgrade the database will no longer be compatible with the old server.
You can upgrade from an older Keycloak version to a more recent one by using the official Keycloak documentation, Upgrading Guide. Make sure you follow the instructions in each paragraph of the Migration Changes section sequentially, starting from the Keycloak version you’re currently using until you reach the target Keycloak version for the upgrade.
If you need to identify which Keycloak version is used in your installation, sign in to the Keycloak Admin Console and verify the Server Info for the master realm .
