The selected replica has one or more databases in the initializing or reverting state. Failing over to this replica will cause these databases to be marked suspect and fail to come online as they are partially rolled back from the previous failover. If you continue, they will need to be removed from the availability group, restore from a previous backup, and re-added to the availability group to resume operations.
