Deployment Migrate Phase
Applies to: Office 365 Dedicated Plans
Topic Last Modified: 2012-12-10
The Migrate Phase begins after your organization has successfully completed its pilot testing and ends with completion of the service continuity failover exercise.
Major tasks and milestones completed by your organization and Microsoft during the Migrate Phase are listed below.
Start and complete velocity mailbox migrations.
Conduct the disaster recovery failover exercise.
Transition the deployment project to the Microsoft Service Delivery Manager.
Disable your Office 365 users on the source BlackBerry® Enterprise Server.
Turn off scheduling for resource mailboxes prior to mailbox migrations.
Re-activate BlackBerry devices for your Office 365 users.
Review migration status reports from Microsoft.
Participate in the service continuity failover exercise.
For Exchange-to-Exchange Online migrations, Microsoft uses the Mailbox Migration Tool (MMT) to perform the migrations.
Prior to starting Exchange-to-Exchange Online migrations, your organization is asked to do the following:
- Deactivate BlackBerry device users. You can manage the disabling of users on the source BlackBerry Enterprise Server. After the BlackBerry users are migration to Office 365, you can add them to the Microsoft environment via the BlackBerry Administration Service (BAS).
- Turn off scheduling for resource mailboxes. It is important to turn off resource scheduling (also known as direct booking) for all resource mailboxes (such as conference rooms) prior to mailbox migration. If resource scheduling is not turned off prior to migration, the Resource Booking Attendant setup fails. The MMT can be configured to automatically enable the Resource Booking Attendant as part of the migration functionality.
After migrations are complete, your organization is asked to do the following:
- Review migration status report. Following each migration period, Microsoft sends a Migration Status Report to your deployment team that indicates which user mailboxes were successfully migrated and which were not. It also describes what actions to take where applicable. If a mailbox is not successfully migrated, it can be rescheduled for another attempt after your project team either fixes the issue, or works with the end user to fix the issue. User mailboxes may not be moved for such reasons as oversize mailboxes, exceeding the "bad items" limit, and issues related to your Active Directory environment.
- Reactivate BlackBerry service on devices. Microsoft will provide your organization with the specific guidance and settings required for users to access to the BlackBerry service. Your BlackBerry users must follow the activation steps to enable their BlackBerry devices to synchronize after migration.
- Add multiple BlackBerry user accounts. Within BAS, you can use a .csv file to perform an import of multiple user accounts into the BlackBerry Enterprise Server after the migration. For more information, see Importing a list of user accounts to a BlackBerry Enterprise Server.
