Hello can the 5508-12 be converted into a standby HA controller? Cisco is abiguously saying that 50 permanent licenses are needed on a standby controller.
Does it mean we need 50 base licences (so only 5508-50 and above) or 50 licenses as any combination of base + adder licences?
There are two things, to add another controller in HA,
1. Either the controller which is assuming the role of Secondary got Permanent AP count license
2. buy a HA SKU controller License for a controller which has got no other license.
What's the process to convert? I have a customer who bought a second 5508 with 12 licenses and now wants to install as HA SSO.
