- Backup Database
- Shut down one instance of DM and take it out of F5 rotation
- Upgrade RHEL on this node
- Upgrade EAP to 7.2
- Remove CAS parameters from the starting script
- Shut down the second DM node so both of the instances are down and put it out of F5 rotation
- Apply migration database script (added as file in this ticket)
- Start the service and on the migrated node pray for its success
- Put the migrated node back to F5 rotation so the outage ends
- Repeat migration steps on the second node (skip the database migration steps as it has already been done during the first node )
