    What's the "on phases" do you mean?
    If you mean on-premise Exchange cross-forest migration, an easy method is to migrating the PST file:

    1. Export the mailbox to PST file
    2. Move the file to new server
    3. Create mailbox in new server
    4. Import data from PST file to new mailboxes: Procedures for mailbox imports from .pst files in Exchange Server
      Or you can follow this blog to perform a cross-forest migration: http://old.moh10ly.com/blog/powershell/preparing-migrating-users-and-handling-contacts-between-two-forests-in-microsoft-exchange-cross-forest-migration
