A customer has this setup:
Onprem Exhange 2010 SP3
AdConnect sync working
Office 365: All users licensed and have mailboxes (that they not use yet)
For now they only use 365 for donwloading and installing Office PC applications.
Now they want to move their Exchange system to Office 365 as well. They insist on using Migrationwiz for transfering mailbox data, and they want to do it in batches/stages.
Which solution should we choose? Hybrid or staged and how about the mailflow when some mailboxes are transfered to 365 and other mailboxes are not and how will onprem/365 know when a mailbox is transfered if using migrationwiz for copying data.
