The controller is end of sales and end of support. That means that no support contracts are available any longer.
All download pages for legacy HPE networking products were moved to asp.arubanetworks.com but for some reason this was not done for MSM so there is no download page at the moment. Maybe due to the fact that MSM was already end of sales when the migration was done.
22.214.171.124 and 126.96.36.199 are relatively close to each other. Maybe if you have a premium license you can enable teaming. If the controller with 188.8.131.52 is team manager and you add the other controller to the team, the team manager will upgrade the team member to the same version automatically.
The last version for MSM is 184.108.40.206 from May 2019. It will require an upgrade in steps so you need to also find the intermediate firmware. If your controller is not already running Version 220.127.116.11 or 18.104.22.168 or later, a two-step upgrade must be performed. First upgrade your controller to Version 22.214.171.124 or 126.96.36.199, and then as a second step, upgrade the controller to V188.8.131.52
The upgrade will also introduce a lot of changes and new features and this can be sometimes challenging. Especially given the fact that there is no support. If the WLAN is stable with 184.108.40.206 and you don't need any new features maybe its better to stay with 220.127.116.11.

Subject: Upgrading Wifi-controller MSM760
I have a MSM760 with 70 attached access-points.
Very pleased with it, so I bought a spare one - just in case.
The one I just aquired has a lower firmware-version 18.104.22.168
The one I'm running in production now is 22.214.171.124 I would like the newly aquired one to run at least the same version. So I have two questions
To upgrade either one of them, do I need some kind of service-contract?
I can't seem to find the software on the hpe.com-website
Would you recommend to upgrade all the way up to the newest version, if I find a way to do it?
