I don’t see this covered anywhere. I presume that one must never restore settings from one model to a different model or bad things could happen.
However I also presume that restoring access control settings saved from one model can indeed by uploaded to a different model.
I also presume it would be wisest to make sure the two different models were running the same firmware.
In my case I am upgrading from Newifi D2 to PW Ax1800. Obviously it would be great to upload as much as possible, but common sense warns me to be careful.
Thank you
NOTE: it is well documented that Toronto-N model has some special restrictions when updating fromearlier software to later software given WiFi upgrade. Not relevant for me.
