I've just deployed a new Aruba controller 7205 with the OS 22.214.171.124.
Should i need to upgrade this version to the Aruba recommended one? If yes which one?
Appreciate your kindly help
Whether or not you upgrade will depend on if your access points need it to function or if there is an existing vulnerability or bug that affects you.
On asp.arubanetworks.com I would choose the LSR (Long Supported Release) checkbox and look at the release notes to make sure your controller and access points are supported.
Something to add...
To evaluate which version of code is supported with which AP Series, here is a matrix which helps you with the solution - https://www.arubanetworks.com/assets/matrix/matrix_WLAN-platforms-software-support-matrix.pdf
It is always recommended to use an Long Supported Release which is 8.10.x Code train and from this the most recent version. That is 126.96.36.199 as of today.
