I have to do an SQL Server 2005 domain migration & renaming
Is my checklist complete?
Is there an impact if the "Database Owner" is from the old domain?
security tab of the sql server:
check old domain groups/add new domain groups
deactivate all sql services
change the service accounts to the new domain accounts
change the domain of the server
Reboot and activate the deactivated services.
--Rename SQL Server with default instance
Pre-Step Delete all your maintenance plans and recreate them after you changed the name
sp_addserver <new_name>, local
