Rigth now, My company has 1 PDC called MainServer, 1 BDC called BDCMain.
In the PDC (MainServer) we have installed Exchange 5.5.
Because of performance (hard disk issues, memory, etc) I need to install a new server that will replace the PDC.
Could you please explain me what steps I must do in order to make this instalation succesful ?
All I need to keep is the trust relationships between the MainServer and others, all the user accounts and If its possible their mailboxes.
