I have successfully completed all the steps in migration from SBS08 to SBS11, and I was trying to demote the old SBS08 server.
1: I removed the cert services from the SBS08 server.
2: When running dcpromo to remove the SBS08 server I recieve the following error:
"The directory service was unable to transfer ownership of one or more floating single-master operations roles to other servers"
When I run the following command on the SBS08 server netdom query fsmo I get the following.
Schema Master: SBS11.xxx.local
Domain Naming Master SBS08.xx.local
PDC SBS08.xx.local
RID Pool manager SBS11.xx.local
Infastructure Master SBS11.xx.local
Any help would be greatly appreciated.
