Single Domain migration to Office365 - leaving remaining domains on-premise


I have an Exchange 2007 server on premise which hosts multiple mailboxes on multiple primary email domains.

I want to migrate all of the mailboxes on only one of the domains,, away from my on premise and to Office365.
I want to leave the remaining mailboxes, who do not have email addresses with on premise.
I also want to be able to migrate any dist. groups or public folders related to

What is the right migration method for this scenario? A cutover? (of sorts)

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If you are fine with (temporary) hiding all the other recipients from the GAL, you can go with Cutover. Otherwise do a staged, and recreate any DLs as needed.
