The Domino server offers two methods of migration from Microsoft Exchange to IBM Lotus Notes and Domino 8 as follows:

  1. Server-to-server migration with the help of Domino upgrade service - Domino Upgrade Services in the Domino Administrator client allows migration information from existing Microsoft Exchange messaging and directory system to Lotus Domino R8. With Domino Upgrade Services, you can import users from the foreign directory, register them as Notes users, and then convert the mail from Microsoft Exchange mail system to a Domino mail database. The migration tool lets you migrate all users and/or selective users from the foreign directory.
  2. Client-to-client migration with the help of Notes upgrade service (Nupgrade) -Notes Upgrade Services works only with a local Microsoft Outlook Personal Storage (PST) file, creating a local NSF file. There is no need to access the servers and thus no update to the server’s primary Domino directory. Although Notes Upgrade Service is designed to migrate Microsoft Exchange data that resides locally in an Outlook PST file, it never accesses the Microsoft Exchange server.
