Question

Dears
I am asking about the firmware upgrade,do i have to upgrade according to path i.e version by version or i can just download the latest version and upgrade it.
Secondly if i upgraded from version to another version without following the path what is the impact?

Hello David,When the upgrade path is not followed ZD does upgrade to the uploaded image although as explained by Martin it would come back with Factory settings. The error image is invalid, not supported is seen on the AP's which let say are on quite old version and are connected to ZD with latest image.

Anytime you don't follow the upgrade path ZD would go to factory state, regarding the downgrade, ZD only supports one down image (that was available previous to upgrade) apart from that image if you downgrade ZD goes to Factory state.

Best Regards
Vineet

Martin, are you sure about that?  My recollection is that if you have a version that’s older than what the documented upgrade path allows, the ZD will let you waste 5-10 minutes uploading the image and then it will tell you that the image is invalid, not supported, or something like that.  At that point the only thing you can do is abort or cancel.

Regarding factory resets - I’ve never seen a ZD do a factory reset when upgrading. As I recall, the only time the ZD will factory reset is when downgrading to an older version that is missing features contained in the release currently on the ZD.

Correct, It will also say that after you have uploaded the image to the ZD.
