DPM During Exchange Migration

[Leon W]

how too use DPM in a Exchange migration scenario.

The situation:
We are going to use DPM to backup Exchange 2007. Our current exchange
version is being backuped by a third party product.

During the migration a multiple exchange 2003 servers are being migrated.
but not one server or database at a time, because of the scale of the
organisation.(20.000+ mailboxes)

How can i manage the sizing of the Recovery point volumes? Because during
the migration the recovery point volume will grow more than it wil ever be in
production.

Is there a way to tune them down after the migration of a server?

The problem is that we are going to run out of diskspace if we leave the
migration recovery points on the DPM server...
Deleting those points will result in data los if something happens during
the migration.

If you are using Server 2008 as your DPM server OS, you can reduce the size
of the volumes. If you are using 2003 as your DPM server OS, you can only
add space, not reduce it.

Rightly said by Michael...

With SP1, DPM support disk migration. So, you could use that feature to
migrate the old volumes to fresh volumes (with reduced size this time)

Now that SP1 is out is there any word on how to perform disk migrations? I
have an old disk set that is not large enough for our stuff now and got some
new disks but would like to keep our existing recovery points and replicas.

Server 2008 w/ DPM 2007 SP1
