DataOntap upgrade and .DAG and SME

[ Edited ]

Plan to to upgrade software on all fileres. These FAS systems are hosting  LUNs for Exchange DAG.

For snapmirror we have to keep the destination filer with same ver or higher. What about for the DAG, Do we have to upgrade the software in all FAS system at same time with same ver?



I appreciate your inputs on this.

If you are running SnapDrive / SnapManager on the Exchange servers, it is important to confirm that the new version of Data OnTap will work with the versions installed - and if not, update those softwares first. Otherwise, the data won't change for Exchange, so the impact is minimal. If possible I would update the filer with the least impacting Exchange DBs just to be on the safe side.
