I have a question and hoping those who have done this migration previously can help me.
We are doing our switchover to the 2010 server this Saturday. Our staff last day is this Friday. I plan on moving their mailboxes after I ensure that connectivity and all is flowing properly to the new 2010.
My question is, majority of the users who are leaving for holiday on Friday have cached accounts and have tablets. What is going to happen if I do the switch over and I move their mailbox and they are off campus? What happens to the mobile devices as well? Will their mail on their tablets stop working until it can sync to the domain, or will they get new certificate warnings when I move our SAN cert to the new server?
