Microsoft SBS 2003 to MS Server 2008 R2 w/ SP1

Posted on 2011-09-15
Last Modified: 2012-08-14
We are upgrading our network to 2008 server mainly for the RDS functionality.  Basically I know I can buy the transition pack to accomplish this but honestly our company doesn't use the server for much more than running a couple programs through mapped drives and using it as the DC of our domain.  We don't use it for DHCP nor do we use it for Exchange or SQL or ISA.

My Question is.  If I create the new server with the same domain.local, IP address, and I add all of the User Accounts to it, can I swap out the old SBS 2003 and install this one then boot up all the computers and not have to rejoin them to the domain?  Will I have to add all the Computer Devices in AD manually or will it populate it?

Let me know.  Thanks.

No you cannot build another machine with the same name and expect the change to be seamless. Computer accounts, like user accounts, have a security context that would prevent things from working as you describe.

With that said, the transition pack was designed to all an SBS server to be changed into a standard server. It is NOT required for a server upgrade scenario. You can take a new server with 2008/R2, promote it as a DC, transfer roles and services, and then decommission the SBS 2003 server. You can use standard server 2003 to 2008 migration guides to accomplish this. You will also want to read exchange 2003 technet articles to oroperly removecand clean up AD as it sounds as though you will not be migrating exchange.

Sounds like it will be easier to just destroy the old Network and rebuild.  There is nothing that is critical and no network setup on the server that needs to remain the same.

So here is another question.  If I leave the new Server with the same domain.local will I have problems if I de-join and re-join the domain?  I only have 9 computers in the office that I have to de-join and re-join.  So to me it would take a lot longer to demote and promote and then do an exchange cleanup.

That depends on your environment. Some applications care, others do nit. Also be aware that building a new domain will mean any files will lose any security/group settings you have set. And will have to be recreated and reassigned as well.

Sounds good thanks Cliff.  The main software they use is going to be upgraded to a new version so it should work properly.  I am also going to carefully look through the file permissions, thanks for reminding me about that.
