Starting Mailbox Migration

Starting Mailbox Migration

To start migrating mailboxes to Microsoft Office 365, perform the following:

  1. Select the Office 365 mailbox migration job in the management tree, and then click the Agent Manager toolbar button.
  2. After that in the agent host pane select the agent host where the agent instance specified for the mailbox collection you plan to migrate is installed.
  3. Finally, right-click the corresponding agent instance from the list of agent instances below and select Start from the shortcut menu.

Note: You can temporarily disable any collection so that it will not be involved in the migration process until you enable it. For that, select Disable in the collection context menu.

You can get track the mailbox migration using the Statistics dashboard. For information on how to do that, refer to the corresponding section of this document.

Post-Migration Activities

Topics:

Redirecting Email to Microsoft Exchange Online

After you finished migrating mailboxes to Microsoft Exchange Online, you may need to update the Mail Exchange (MX) records in your DNS so that all mail is redirected to the cloud. This step can only be performed after all on-premises mailboxes are migrated to Microsoft Exchange Online. Note that this step is mandatory only if you plan to completely decommission your on-premises Exchange infrastructure.

For information on how to do that, go to http://onlinehelp.microsoft.com/en-us/office365-enterprises/ff637598.aspx.

Updating Outlook Profiles

Updating Outlook Profiles

During migration, Migration Manager for Exchange switches mailboxes from the source Exchange server to Microsoft Office 365. Before users can start working with their new cloud mailboxes, their Microsoft Outlook profiles must also be updated. To update Outlook profiles you may use Client Profile Updating Utility (abbreviated to CPUU) shipped with Migration Manager. The utility allows you to update Outlook profiles automatically and transparently.

Caution: You have to provide all users with their Microsoft Office 365 passwords before CPUU switches Outlook profiles. Otherwise, the user cannot log on to his or her mailbox and get an access to his/her emails after the switch.

For information on how to update Outlook profiles using CPUU, see the Client Profile Updating Utility Administrator Guide included in the Migration Manager documentation set.
