How long will my migration take?
We often get asked how long does it take to perform a migration, the honest answer is that it is very difficult to determine exactly how long. Why ?? Well, as both Google and Microsoft Office 365 are cloud based solutions they have to provide a reliable service to most users, so they will often throttle back migration data uploads.
However we do recommend that you get a feel for the duration by sizing your migration before it happens. Sizing your migration consists of performing a test migration ahead of time and using the statistics generated to estimate you initial and cut-over migrations.
Performing these sizing activities does not consume any additional licensing, as long as the same users are migrated during the genuine migration.
