Hoping for some clarification, searching hasn't revealed anything clearly defined.
As titled, 3 SG500 switches in a stack (running in L3 mode), firmware info below
Firmware Version (Active Image): 126.96.36.199
Firmware Version (Non-active): 188.8.131.52
Boot Version: 184.108.40.206
I've read upgrading past v 220.127.116.11 is a no-go without upgrading the boot version. Will I need to downgrade active FW all the way back to 18.104.22.168, then upgrade Boot to 22.214.171.124, then re-upgrade FW to 126.96.36.199 and so-on and so on through each Boot/ FW [188.8.131.52, 184.108.40.206, 220.127.116.11, 18.104.22.168, 22.214.171.124, 126.96.36.199, 188.8.131.52, 184.108.40.206, 220.127.116.11]?
I'll take a backup of running config prior obviously, but will my settings survive this?
Thanks for the input, I'd really like to not brick these switches!
