You may see the following error during the migration:
ERROR: [7347-198-17-00000000] Unmatched left angle bracket in address string: CN=user1@domain.com, Domino User1/OU=DOMINODOMAIN, Domino User2/OU=DOMINODOMAIN, user2 <user2
This error is due to incorrect source data (e.g. mail header or addressbook item).
This error can be safely ignored, as the message is still migrated, but this should still be verified at the target mailbox (Exchange).
