Moving Mailboxes

Hi,

We currently run Exchange 2007 in our organisation.  We have 3 servers running Exchange.  1 is running the CAS and Hun Transport roles, and 2 are running the Mailbox roles in a CCR cluster.

The server with the CAS and Hub Transport roles are running Exchange 2007 SP3 rollup 5 (8.3.213.0)

The Mailbox role servers are running Exchange 2007 SP1.

All servers are running on Windows 2008.

All servers are physical.

I would like to transfer the mailboxes to 2 new servers in a new CCR cluster.  I've read that you can have another cluster pair in the same organisation but if we do this, how does Exchange see the other cluster?

Are we able to migrate a mailbox from 1 database on the existing cluster to a new database on the new cluster or do we have to manually copy the entire database and logs to the new cluster?

Also, if this is possible, would it pose an issue if the new servers were running Windows 2008 R2 SP1 and Exchange 2007 with all the latest service packs and updates?

Thanks

You should have no issues at all moving mailboxes from one CCR to another CCR in your environment. If the CCR's are completely separate they are then seen as 2 separate entities.

Thanks for the reply....

Just to clarify.....we will be able to move individual mailboxes from one database on the current CCR cluster to a new database on the new CCR?

That is correct. Just because they are in a cluster configuration does not mean they have limitations to move between other clusters or other mailbox database for that matter.

Thanks....and last question will it matter if the new cluster has the latest Exchange 2007 updates and the old one doesn't?
