Hi,

I have a SBS2003 box and now a new SBS2011 box. everything runs fine until I get to Migration and DC Promotion then it fails.

I get error " the coputer name has changed and must be restarted to take effect." After the restart I can get DCPROMO.exe to run fine. Am I ok to go ahead using this wizard or do I need to start a fresh formatted install? as the windows help suggests?.

Thanks.

You have to build the SBS 2011 server in Migration mode if you plan to migrate to SBS 2011 from SBS 2003, otherwise it won't work.

If your SBS 2011 server is already built, flatten it and start again.

Have a read of the following migration guide to help you:

Hi, I followed this guide to migrate the server over, but I keep getting the same error. The old server wont demote and allow the new box to become domain controller.

What stage are you at in the migration in his article?

Did you check the health of your DNS / Domain before you started the migration?

Thanks for the help Alan. I ended up having to create a new admin user and everything went over fine.
