Disable/Remove HA

L2 Linker

We currently have a HA pair configured in a data centre and will soon be moving to a new site. For a seemless migration, we were wondering if there are any issues with or considerations we'd need to make if we were to disable HA and remove the HA config, reset and move the passive device to the new site to get it up and running, then move the device from the old DC to the new site and join it as the passive device?


In my head, it seems straight-forward, but want to make sure I havent missed anything.


Thanks in advance.




Need to confirm you did below things


suspend the passive device 

Moved to new DC and power it on and it came back as passive automatically?







from what I can remember:


1. Disabled the HA Preemptive Election setting on both devices

2. Suspend HA on Primary firewall to failover to Passive device

3. Move Primary to new site and reconfigure as necessary

4. Move Secondary to new site

5. Sync changes from Primary to Secondary

6. Re-enable the Preemtive option

Thanks for replying!


We're still in the planning stages, so it'll be some time before we try.


But reading these responses, as well as talking with support and our local sales engineer I'm pretty confident we'll have few issues.



I am trying to do the same thing, darn network team did not advise that the circuits for our SDWAN are independent and thus need firewalls in standalone mode. I disabled the secondary, removed the HA configuration rebooted, and also removed the HA cables that were connected. 

Did the same for the other firewall, bu they are still show in a active/passive mode with no HA
