I need a suggestion on the best way to migrate 32 mailboxes currently on an in-house Exchange server to Microsoft’s Hosted Exchange.
It should be noted we are in another state from the client and we are not currently supporting their Exchange Server, which is handled in-house.
We were originally planning to export their existing mail, calendar, and contacts to PST files and then import after the accounts were set up, but Microsoft is suggesting to the client that we do a cutover migration and referred us to these links for information.
I would like to know what is the best way to handle this migration. Any advice is appreciated.
