I have recommended to a customer using a DFM/OM server for monitoring and another DFM/OM/PM server for Protection Manager backup / restore.
I would like to know if these two activities Monitoring and Backup / Restore must have the same version of DFM?
ie: a fasX can be managed with a DFM 3.6/3.7 for monitoring and a DFM 3.8.1 or 4.0 for Backup / Restore
The underlying question is do we have to align DFM version for monitoring and backup/restore operation?
I suppose no, but after checking our doc, unfortunately we found nothing on this topic.
Thanks for your help.

What is the basis of recommending two different DFM versions for monitoring and Backup/Restore.
Infact Backup/Restore depends upon monitoring.
Moreover huge improvment/features are added in 3.8.1/4.0 with respect to monitoring/Backup/Restore.

There's no reason I know of to need the same DFM versions. Since the monitoring DFM station is only reading data from the storage systems, it ought not cause any issues.
OTOH, it seems it would make your life simpler to use the same version everywhere, unless you're trying to avoid a bug we introduced in the more recent release. 3.8.1 should be very solid -- I don't know of any serious issues with it. You should strongly consider upgrading your monitoring system to 3.8.1.

Hi Richard --
Sorry to get your heart racing. 3.8.1 is relatively imminent, but I don't know the actual planned release date.
Let me put it this way: I can't get bug fixes into 3.8.1 any more because it's too close to the end of it's test phase. But since we want this to be a GA release, the release team is being very careful what they let in and making sure they extensively test to avoid any regressions. The sad, sorry truth of software "engineering" is you add one new bug for every two you fix :-(.

Thanks all for your answers.
What I understand:
- having the same DFM release is not mandatory but recommended
In my case, my customer already have 2 DFM servers running on Solaris.
We are bulding a backup infrastructure based on snapVault and Protection Manager
--> target release for production: 4.0
It was the reason for my request, the customer doesn't target to update DFM and buy 2 new servers for replacing the 2 Solaris.
Thanks to confirm me everything is OK
