4.3.7.Creating migration group(s) and adding group members
In the next step we need to create a migration group and associate our mapped mailboxes with it. Since a migration can be started only on group level, mailboxes that are not group members cannot be processed.
Group management makes the migration process more transparent and manageable. It makes easier to check which mailboxes have been already migrated, and it also helps to define priorities, i.e. to migrate the most important mailboxes in the first round.
Create a migration group and add members to it:
Navigate to “Group management” tab. As you can see, The Groups pane is initially empty. Click “Create group” in the toolbar to create a group.

Name the group and add members to it using the context menu:

The next pop-up dialog displays all available mappings that can be added to the group. Pick the desired mappings and click “Select”.

Mailboxes to be migrated are now added to the “Members of group” grid as seen on the picture below:

The “Jobs of group” grid is still empty. In the following subchapter we will learn how to add a migration job to our migration group. There will be 2 jobs created: 1st for email migration, 2nd for shortcut migration (shortcut conversion).
