Thanks for clearing that up. Just to confirm, I can run two 7205 in HA using the redundancy option?
Thank you

It is just updated wording. Mobility Master is now Mobility Conductor, and a few other verbiage changes came such as blacklist is now denylist, among a few others. It can be inconsistent depending what documentation you are reading.
Clustering requires a Mobility Master/Conductor, which manages your "managed devices" which would be your two 7205s.

Hello everyone,
I currently have one 7205 MC at version 8.9 with plans to order another one shortly. Although we don't have a big network (30 APs), we need to add some sort of HA to the network due to the type of industry we are supporting.
From my understanding, the HA (Configuration --> Redundancy) is the legacy method and clustering is the preferred method. After reading some documentation and watching some videos, the HA method looked simple enough. I noticed though on our controller running 8.9 that under Configuration --> Redundancy, it mentions "Conductor Redundancy" instead of "Master Redundancy" as shown in the documentation and videos. Does this mean we would need an Aruba Mobility Conductor to use this feature? Or is just updated wording?
In the ArubaOS 8.9.0 user guide, it mentions that clustering is only supported on the Mobility Conductor.
My question is, can I do any sort of HA or Clustering with just 2 x standalone 7205s?
Thank you very much.
