Mail Cutover for Large Organizations

​​When you’re migrating more than 100 people, it often doesn’t make sense to cut over from the old system to the new one all at once. Unfortunately, DNS only offers limited options for configuring MX records. Some organizations can take advantage of hybrid deployment and staged migration, but these cases are rare. For everyone else, we’ll set up your migration batches so that the bulk of users’ e-mail will be transferred in an orderly way, followed by much faster “delta sync” that can be performed for a much larger number of users of on the day before the cutover or shortly after.
