we are in the process of carrying out a SBS2003 STANDARD. TO SBS2008 STANDARD. MIGRATION. Microsoft comment on their instructions that both Source and Destination Servers must be connected to the Network and the gpupdate /force command run on each Client PC BEFORE the source Server is demoted and disconnected - if the Client PC's are connected AFTER demotion of the Source Server can we still run the gpupdate /force command? - and what issues will we have on the Client PC's if we run this command after the Source Server has been demoted?
Basically, we have a ghost copy of the Clients Server in our offices, not currently connected to most of the Client PC's, from which we are carrying out the migration, and need to confirm the above before we issue the Demotion commands and install the SBS2008 box into the Clients premises..
