 If an upgrade of a cluster fails, you can manually log in to the cluster and use the backup to return the cluster to its preupgrade state. There are two stages:
 
 Rollback:: If the attempted upgrade included a change to the platform OS deployment, you must roll back to the previous version before running the recovery script.
+
+[IMPORTANT]
+====
+A rollback is only applicable to upgrades from TALM and single-node OpenShift. This process does not apply to rollbacks from any other upgrade type.
+====
+
 Recovery:: The recovery shuts down containers and uses files from the backup partition to relaunch containers and restore clusters.
