I am planning an upgrade to HiveManager form 6.1r3a to 6.4r2 so we can use AP230 Aerohives. Our existing network has mixture AP120 an AP121.
I would like to keep the number of AP firmware/config updates to minimum and so reduce the number of AP restarts. Can just upgrade straight to 6.4r2?
Or what the most effect upgrade path? (eg 6.1r3a>6.1r5>6.1r6>6.4r2 with a AP config update and reboot at each revision).
