Change HA pair from Active/passive to Active Active

Hi All,

 

I will be changing one pair of our firewalls from an active/passive pair to an active/active pair. Whilst confident of what is needed and the process I need to take, has anyone ever gone through this process? Was it problematic, time consuming, any gotchas I should know about?

 

Regards

@a.jones,

The few times I've needed to do something like this it was highly controlled to avoid any splitbrain situations, as you'll need to temporarily break HA as you switch everything over. The best advice I could give you would be to configure everything on one of the devices while it's essentially fully disconnected from your network. You can leave the management interface and the HA interfaces plugged in so the pairs can still communicate, but unplug or shutdown every other connection to avoid any routing issues.
