m4300 firmware upgrade without killing entire network?
https://community.netgear.com/t5/Managed-Switches/m4300-firmware-upgrade-without-killing-entire-network/m-p/2160873 Since I am about to update (12.0.13.8 -> 12.0.17.7) several stacks with 8 modules ...
It would be best that you do the firmware upgrade in a ladderized manner. From v12.0.13.8 upgrade it to v12.0.15.7. Then from v12.0.15.7, upgrade it to v12.0.17.6 and so on until you reached the latest firmware which is v12.0.17.7.
Also, it would be best to perform the upgrade the firmware during non-production hours.

It is very interesting that nothing of this update path is mentioned in the release notes. But yes, we will implement this path like this. However, there is still the question discussed in this [https://community.netgear.com/t5/Managed-Switches/m4300-firmware-upgrade-without-killing-entire-network/m-p/2160873] article, how and when the individual modules should be updated or restarted?
In the end, we are happy if there are no defective modules that have to be replaced by netgear.
