I have a customer on EV 10 for Exchange and they have the need to migrate off the on-premise exchange 2010 and EV 10 environment. They have chosen to go to Office 365 / Exchange Online w/ archival licensing. Can I please get some recommendations on migration options for their 4TB of archive data (Journal and User Archive). They have been stubbing all archived messages for quite some time.
I understand that it is possible to restore each users archive to the on-premise exchange 2010 mailbox assuming there is space. The export to .PST format and utilize a PST Capture like tool to push up to the Office 365 cloud account.
This is time consuming and since these users stub their archived messages and have moved stubs around to folder for organizational purposes. When the archive is restored mail returns to the point it was archived from not necessarily the same folder as the stub.
Thank you
