Hello, I have two RUT950 routers, both having firmware RUT9_R_00.07.01.1, exactly same as mentioned in one of the files inside back-up.
I am trying to restore configuration backup, but I get error message "The selected back-up file is not compatible with this device, please choose another file". This happens with one of the routers, with the other one accepts the back-up.
What is causing this error? I noticed that though the routers have exactly same firmware, the build firmware build date differs. Does router need to have exatcly same firmware as the one back-up was made from?
