Hi
I have a client that is about to spin off part of their business. The spun off part will have their own separate domain and resources. They currently have their own mail domain (say qwerty.com) and they are currently using the parent companies (say parent.com) Exchange 2003 server, I will have access to the Exchange server but clearly only wish to move the users of qwerty.com. They will be moving to Office365 so I would like to use the migration tool. Does anyone forsee any difficulties in this? I assume that I can select only the users I want to move and move only the qwerty.com mx records and leave the parent.com mailboxes on the Exchange 2003 server. They do not have public folders.
I have migrated a few companies in the past but not partially only a full cutover.
Any thoughts would be appreciated.
Adrian
