CanBus on AIO V4

Hello, to start with, I have an already existing AIO v4.5 board that was used with a conventional cytron and phidgets. I am now wanting to switch the tractor that it is in currently with a Valtra s353 so I got some questions that I cannot find an anwear for.
-Is the board CanBus ready as it is (previously configured for a cytron and phidgets), or do I have to buy some sensors, valves, relays etc.?
-Do I need to solder anything to the board?
-Do I still need a WAS

Thank you for help and sorry if these questions were already answered but I cannot find it anywhere.
