5508-12 HA Licensing

[Todd Bren]

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?

Thanks!

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

or,

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.

Thanks
