Premigration considerations

Before you start the migration process, review the following considerations.

Enable onboarding in the destination MDM domain

  • Onboarding is the process of activating users’ BlackBerry devices after user accounts are moved to the BlackBerry Enterprise Server for Microsoft Office 365. By default, onboarding is disabled for the BlackBerry Enterprise Server for Microsoft Office 365. To enable onboarding, see Enable onboarding for the destination MDM domain.

State of the source domain and the destination domain

  • The destination domain must use a different SRP ID than the source domain.
  • Before you use the BlackBerry Enterprise Transporter for Microsoft Office 365 for the first time, log in to the BlackBerry Administration Service of the destination domain and verify that you can create a user account, assign a BlackBerry device to the user account, and activate the device.
  • Verify that the destination BlackBerry Administration Service is running. If the destination BlackBerry Administration Service is not running while you are moving user accounts, the default assignments for groups, IT policies, and software configurations might not be applied.

Performance impact

  • The first time you run the migration process with a new source domain, the destination domain must catalogue SRP IDs and authorize the source domain before the migration starts. This process can take up to 10 minutes. This delay does not occur when you run subsequent migrations with the same source domain.
  • The amount of time required to complete the migration and device activation process varies based on a number of factors, including the number of user accounts that you want to migrate, the number of configuration assignments (groups, IT policies, and software configurations), the user activity in the destination domain, and overall network traffic. To minimize the impact on your organization's environment, it is a best practice to run the migration process during low-usage periods.
  • If the source BlackBerry Enterprise Server is earlier than version 4.1.6 MR5, the tool might require more time than expected to move user accounts to the destination domain.

One-way migration

  • As a result of the onboarding process, once you migrate a user account to the BlackBerry Enterprise Server for Microsoft Office 365, you cannot move that user account back to the source domain, or to a different MDM domain that does not use the BlackBerry Enterprise Server for Microsoft Office 365.

Initializing users on the destination domain

  • During migration, there might be a delay before the destination domain applies the selected IT policies or group-assigned IT policies to user accounts. During this delay, the Default IT policy of the destination domain is applied.

BlackBerry Device Software

  • If the user accounts in the source domain have BlackBerry devices that run BlackBerry Device Software 4.3.0 or earlier, IT policies might not be applied to the devices during the migration process. Before you move the user accounts, update the BlackBerry Device Software on devices to version 4.5.0 or later. Another option is to run the BlackBerry Enterprise Transporter with the Ignore Warnings check box selected, and activate the user accounts again on the destination domain. You do not have to permanently delete the data on the devices before you activate the user accounts again.

BlackBerry Enterprise Server Express as the source domain

  • If a user account is associated with a device that was provisioned using the BlackBerry Internet Service, you cannot migrate the user account to the BlackBerry Enterprise Server for Microsoft Office 365. The BlackBerry Enterprise Server for Microsoft Office 365 does not support devices that are provisioned using the BlackBerry Internet Service.
