firmware upgrade on m5300 stack advice needed

[robfantini]

Hello,

we are trying to upgrade firmware on our 2 switch stack .

after uploading and reset power we have ' Code Mismatch'

unit 1  has  11.0.0.40 

unit 2 has   11.0.0.31 

Unit 2 is active.

Could we get advise to fix this issue?

thanks

i just read https://community.netgear.com/t5/Managed-Switches/M5300-stack-firmware-upgrade/m-p/1424976#M4850

and realized that both switches probably did not get a power reset.   will try that tomorrow.

reboot of the switch running the older code  fixed the issue.

note that after fw is updated,  rebooting one switch at at time works. choosing all is as far as I remember was done after the new fw was uploaded.
