+2Hi guys;
i need some help about this,
I perform a feature release update today, but after that my main production cluster server stop working telling me that one of the server in the cluster is in another version of the software, which its true.
But my questions is If I perform a DR restore to the moment before the update start will my commserve perform a downgrade to the version it was before the update.

Hi
When you perform an FR update on the Commserve two things happen:
If you perform a DR restore, the database would be back to the earlier FR version, but the binaries would not. Depending on the type of clustering in use, you could end up with mis-matched binaries and database across the nodes.
If you wanted to roll back completely to the earlier FR level when the DR backup was taken, you would need to perform a full uninstall and reinstall with the previous version, then perform a Commserve DR recovery operation.
I suggest if you’re having difficulties with the Commserve post update, let’s address those issues as it’s likely a cleaner and faster fix than roll back.
If these issues are having an impact to your operations, raising a support case is the best way to get the help you need and fastest resolution.
Thanks,
Stuart

When you say this “ If you wanted to roll back completely to the earlier FR level when the DR backup was taken, you would need to perform a full uninstall and reinstall with the previous version, then perform a Commserve DR recovery operation”.
Do i have to perform the process on the main CS server and all MA before to do such task or only in the CS?
And about the binaries if I perform the restored should all MA and they going back to version of FR if I repair them.
+23In any version reverting, you have to uninstall the software on the CS (be sure the database copy is safely elsewhere), install the older version that matches the database you plan to restore, then restore the db.
This way, they are all in synch.
Now, that db likely thinks the MAs are of an earlier version as well, so you may have to do the same process, sans the db restore on the MA(s).
