Migration Types and Which Applies to You
The route depends on where you are coming from and how much history you need. Picking the wrong one usually shows up as a very long cutover weekend.
- 01Cutover migration: everything moves at once. Best for smaller businesses and the simplest to reason about
- 02Staged migration: users move in batches while both systems run. Suits larger estates that cannot take a single switch
- 03Hybrid: on-premise Exchange and cloud coexist for a period, used where a phased move is unavoidable
- 04IMAP migration: the fallback from cPanel, Zimbra or other hosts. Moves mail but not calendars or contacts, which have to be handled separately
