One of our customer raised the below query:
We have only 2 single domain forests. So only ‘forest A’ and ‘forest B’.
The users in both are to be moved to ‘forest NEW’. Customer is looking to use sid history hoping it may make things easier.
Customer wants to gradually move the mailboxes of these users to Exchange online, in parallel to their move to Forest NEW.
What are the (im)possibilities that result from the desire to perform the user and exchange online migration at the same time?
Any inputs would be of great help.
Many thanks in advance!!
