What are the steps to do a migration in gateway mode? Is their documentation for that scenario? I have seen the post that refers to the admin guide for server mode only and the manual does not cover gateway mode at all. Does the firmware need to be identical? Please advise.

Will these 2 mode are very different

1: I would start by exporting the users from the server-mode unit( mail data backup )

2: on the actually mail-server, you will need the mbox crafted

3: it's a good time to use LDAP for recipient verification

4: and lastly lift all policies and walk-them over to the FML acting as gateway

5: monitor the new installation rollback to server mode if you see any weirdness

6: keep the old server-mode FML install ( but don not receive mail or process mail ), so users can login into it to collect data ( contact, mail,etc.....)

I believe support has some ad-hoc tools for moving things around but open a ticket to see what they have.

That's the 10k foot but that 's what I would do.

If the 100C was gateway mode then you may not care about quarantine mail on the 100C. In 5.4 you can just restore the older config even from a different platform. Some options may have changed so it's a good idea to verify the config after the restore.
