Our company is in the middle of an acquisition.
Due to the number of people in one of the offices we are acquiring want to keep their exchange server intact for mail flow and mail storage but still move them from their domain/forest into ours. This includes their exchange server and client machines.
We are running Exchange 2007 in compatibility mode with Exchange 2000/2003 in our main office.
The company we purchased is running Exchange 2003 on its own domain.
We are looking to:
" Move their server/clients onto our domain
" Leave their Information Stores on their existing Exchange 2003 server but somehow bring that server into our existing exchange environment.
" We would like to avoid re-installing exchange on their server.
We are NOT looking to:
" Move their mailboxes onto our servers
" Rebuild their server or migrate their mailboxes to another server.
We can assume that:
" All clients account names will change and need to be re-mapped to their mailbox
I'm looking for some direction, white papers and any ideas on how to go about this.
