Firmware upgrade C9200L recomanded version

[kralopafo]

Hello

I'm planing to perform firmware upgrade of our C9200L switches, including:

One stacked (StackWise) switch, consisting of two C9200L-48T-4X (Active/Standby) , acting as Distribution switch.

- Currently on 16.11.1 CAT9K_LITE_IOSXE , INSTALL mode

6x standalone C9200L-48P-4X, one per each floor, acting as access switches.

- most of then are on versions 16.9.4, 16.9.07, in BUNDLE mode

I would like to kindly ask you, for your advice, which version should I choose in this scenario.

I was considering cat9k_lite_iosxe.17.06.05.SPA.

But to be honest, I didn't went through opened TAC cases or announced problem in particular versions, so I would really appreciate your experienced advice.

Also any of your advice about stack upgrade/ installation process I would highly appreciate, since I'm going to upgrade stack for a very first time.

Thank you very much.
