Early Adopters
Begin migrating user mail data
Level of Effort:
Moderate to High (depending on tool used)
You should migrate mail data for your IT team, your early adopters, and as many
additional users as possible during this phase. Most of the migration tools provided by
Google allow you to migrate calendars and contacts at the same time you migrate
mail.
At first, you should migrate mail in batches of five to seven users. Timing these
batches helps you get a sense of how long it will take to migrate mail for all of your
users.

Consult the documentation for the email migration tool you selected during the
