Migrate FTD 7.4 HA pair to a New FMC

 Migrate FTD 7.4 HA pair to a New FMC

FTD-74-A and FTD-74-B are deployed in an HA pair and currently managed by FMC-1. The objective is to migrate both FTDs to FMC-2.

1. Prepare and Reassign FTD-74-A

Remove the existing manager (FMC-1).

Register FMC-2 as the new manager.

2. Register Devices on FMC-2

On FMC-2, register FTD-74-A and assign the “Initial Discovery ACP”.

FMC-2 should detect that FTD-74-A is part of an HA pair and automatically create the HA configuration.

FMC-2 will then attempt to automatically register FTD-74-B.

• If the HA registration fails, FMC-2 will unregister FTD-74-A.

•  If the process is successful, both FTDs will appear in FMC-2 as an HA pair.

3. Post‑Migration Configuration

Reassign interfaces to the appropriate security zones.

Restore default routing.

Apply the correct Access Control Policy (ACP).

• The ACP can be exported or recreated from FMC-1, if required.
