  • Ensure that your
    BlackBerry Dynamics
     connectivity profile is configured to route traffic for your email and authentication servers. Depending on your organization's routing requirements, this might mean one of the following:
    • The authentication and email traffic must route through your internal network
      : If your organization requires traffic to be routed internally (for example, your authentication server is not accessible publicly, or security requirements or conditional access policies require internal routing), you should ensure that the following hosts are added to the "Additional Servers" section of the connectivity profile (ensure that the route entries are configured for
      BlackBerry Proxy
      ):
      • Internal
        Microsoft Exchange Server
      • Microsoft Office 365
         server (outlook.office365.com)
      • Microsoft
        's Content Distribution servers (such as aad.cdn.mstauth.net)
      • Authentication server (such as your
        Active Directory
         Federation Services (ADFS) server,
        PingFederate
         server, or Okta server)
    • The authentication and email traffic does not have to route through your internal network
      :  If your organization does not require routing these connections internally, to improve performance have these connections routed Direct instead. If your Default Route is set to Direct, then you do not need to specify any servers. If the "Default Route" is set to "BlackBerry Proxy" or "Block", then you must add the servers specified above to the "Additional Servers" list, but specify the route type as "Direct" instead.
    For more information, about the
    BlackBerry Dynamics
     connectivity profile settings, see the BlackBerry UEM Managing apps content.
  • Ensure that your organization’s app configuration is set up for Modern Authentication,
    Microsoft Exchange Online
     endpoints (
    Exchange ActiveSync
    , Exchange Web Services) and Autodiscover. For more information, see BlackBerry Work app configuration settings, and the Modern Authentication Guide.
  • This feature requires
    BlackBerry Work
     version 3.2 or later.  Older versions of the app will immediately have the
    Microsoft Office 365
     settings applied to them. To view a list of installed
    BlackBerry Work
     client version, see Export BlackBerry Dynamics app reports to a CSV file in the
    BlackBerry UEM
     Monitoring and reporting content.
  1. On the menu bar, click
    Apps
    .
  2. Click the
    BlackBerry Work
     app.
  3. Click the name of your organization’s app configuration.
  4. On the
    Advanced Configuration
     tab, select the
    Migration Flow Enabled
     option.
  5. To set an expiry time, enter a date in the
    Migration Flow Expiration Date
     field. After the date that you enter has passed, the Migration Flow Enabled setting is ignored.
  6. Click
    Save
    .
  7. Assign the new app configuration to users who will be migrated to
    Microsoft Exchange Online
    . If you are migrating users in batches, assign the new configuration prior to migrating users.
After you have migrated all of your users’ mailboxes, you can deselect the
Migration Flow Enabled
 option.
To ensure that your environment is configured correctly,
BlackBerry
 recommends performing a test migration with only a few users before you perform a larger migration of users. 
If a new
BlackBerry Work
 user is activated against an app configuration that has the "Migration Flow Enabled" option set, the device will immediately pick up the modern authentication and
Microsoft Exchange
 endpoint configurations.
BlackBerry
 recommends that you either create a new app configuration to apply to users who will be or already are migrated to
Microsoft Office 365
, and have a separate app configuration for users who will continue to use an on-premises
Microsoft Exchange Server
.
