I need to migrate an existing SBS 2003 system to a new Windows Server 2008
box, which will also be running Exchange 2007. As I will not be retaining
any of the 2003 software I would prefer to avoid the expense of the
Transition Pack for SBS. I have read some conflicting / confusing advice on
the best route for making this transition - here is the process as I
understand it but I would appreciate any comments, particularly if I have
missed something obvious.
My plan is:
* Add the new 2008 server as a member server in the existing SBS 2003 domain.
* Run adprep on the SBS to update the AD schema.
* Promote the 2008 box to being an additional Domain Controller. I believe
that I have to do this before installing Exchange otherwise the promotion to
DC breaks Exchange.
* Install Exchange 2007 on the Server 2008 box and add to the domain.
* Move data to the new server.
* Transition mailboxes to the new server.
* Move group policies etc. to 2008 server.
* Transition FSMO roles from SBS 2003 to 2008 server.
* Remove SBS 2003 server from domain.
Does this plan look anything like sensible, or have I missed anything
important? Any help or comments much appreciated.
