We're looking to migrate all of our mailboxes etc onto Office 365 from Exchange 2010. We aim to still primarily use our local Exchange 2010 setup however, the office 365 setup will act as a 'live backup'. This meaning, if our local exchange 2010 setup were to go down, we could instantly start using the Office 365 setup without any downtime.
So in short, I'm here to ask if it's possible to migrate all of our Exchange 2010 data to Office 365 in the aforementioned fashion while maintaining synchronisation between the two?
Kind regards,
