If you do not wish to add individual profile pairs for migration you can choose to use the Migrate All User Profiles feature. Before attempting this sort of migration, you should familiarize yourself with the expected behavior and limitations, below.
When performing an All Profiles migration, the client PC is scanned for profiles. The destination context is then searched for usernames that match these profiles. All profiles with matching usernames are marked for migration to the destination context. If a matching destination account cannot be found, a warning is logged.
To migrate All Profiles for one computer, enter '*ALL' as both the source and destination usernames with the Add New Profile Migration form.
You can also set all computers to migrate all profiles with the Migrate all user profiles option on the Import File and Import from Active Directory forms.
