Migrate PA-3260 cluster to 3420 (managed by panorama both)

BigPalo — Fri, 20 Feb 2026 06:26:01 GMT

Hi, i have to do this migration.

So my steps will be:

1) Install the same version 11.1.x as the old cluster.

2) install licenses

3) add new cluster tu panorama

3) add the device group old cluster to the new one.

5) clone template old cluster to the new one cluster and check the possible interfaces/clusterHA-ID changes to the new cluster.

IS that procedure correct. Woul you recommend or change anything?

That process should be pretty solid

1.1) update content and antivirus

1.2) install plugins if any

Make sure you double-check if there are any variables being used and theyre copied over to the new devices
