Architecture
The following diagram illustrates how Google Apps Migration for Microsoft
®
Exchange gets
users’ data and migrates it to Google Apps.
1. The utility reads the list of users you want to migrate.
You create the list of users ahead of time.
N threads are processed simultaneously according to your configuration. For example, if
you configure the utility to process 25 users at a time, then 25 threads are spawned. As
soon as a thread finishes processing a user, it moves to the next one available from the
list.
2. Using the information you provide in the migration wizard, the utility opens the message
store or PST file for each user identified in the list.
3. The utility retrieves mail (and optionally for Microsoft ® Exchange, calendar and contact)
data for each user.
