SBS 2003 to Server 2008r2 and changing domain name

Posted on 2012-08-23

Long time reader, second time asking a question.  Any tips or advice on this upcoming project is much appreciated.

I have an old SBS 2003 w/Exchange 2003 server that needs to be replaced.  We have also recently changed the firm name so during this transition I'd like to change the domain name.  I have about 28 users all on new Win7 machines.  

In anticipation of server 2012, and having to move away from the SBS environment, i'm upgrading to 2008r2 Standard w/SA and i'll wait for SP1 to be ready before thinking of putting that into production.  

I'm also upgrading from Exch 2003 to 2010, again with SA and down the road will upgrade to Exch 15 when the time is right.  

I do not need to worry about RWW or the SQL on the SBS box, as i have a second 2003 standard server with SQL 2005 running apps that will stay in place for now.

The new Standard 2008r2 server will be my only domain controller, host AD & Exchange and maybe some printer sharing.  The server will be installed as VM using VMware.

I've read some articles on moving from SBS 2003 to 2008 Standard, but nothing involving a domain name change.  

Any tips or advice and or great links and articles to follow up on is much appreciated.  FYI, i've been in the IT field for several years, but this will be my first migration of both SBS and Exchange.

    You simply won't be able to do what you want. Renaming a domain out from under exchange will break a lot of things.

    You do have options. You can build up a temp DC and temp exchange server, decommission SBS, then stand up your new final DC with the new AD domain and establish a domain trust to move accounts over  (SBS does not allow or support trusts which is why it must be retired before doing this,)

    Or you can build up your new network and jump through a lot of ADMT and exchange hoops to export and import the data.

    Regardless, all workstations and member servers will also need to be touched.

    I'd look into and get a support kit. Talk to them ahead of time because your plan will be an edge case. I know they'll support such a migration, but it isn't one of their standard kits so you'll want to let them k ow what you want and let them assist you on building a plan tailored to your needs. That'd be my recommendation.

    The only documentation for doing a domain name change during the migration that I am aware of is by buying a migration kit, specifically for your scenario, from
    They provide customized instructions, tools, and 90 days support for the migration for $395.

    Thanks for the quick feedback.  I was already assuming it would be a PITA, but just wanted some reassurance that I was right.  Maybe i can talk the partners out of changing the local domain.
