Process to change to HA from cold spare

L0 Member

The HA documentation states that one should start with a 'clean slate' when implementing HA. I currently have one PA-500 in production on 4.1.4 and another PA-500 as a cold spare. The production PA-500 has 2 unused traffic ports that can be used for HA. I would like to know what the least disruptive process is to change from cold spare to active-passive HA. (I've been told by our firewall vendor that active-active "is a mess")

Do you have your HA licensing, and have you ever configured your cold spare?

You would have to go through Sales first as a cold spare is typically used to replace your production unit in case of failure. To enable HA on both units, the cold spare has to be considered a 'production' device and only Sales can offer more insight on that aspect. Once you have the cold spare tag removed, HA options would then made available to you.

The units were purchased as an HA pair but the HA part was never implemented.

That makes it easier then. I assume you also purchased TP and/or URL licensing to match the current production device. That being said, you should be able to configure HA using one of the KB articles or utilizing the admin guide on the PAN device.
