Vista vs goggles integra

Having just purchased a pair of integra goggles I’m now trying to connect them to my vista… I understand they have to be on the same firmware version but, my vista has WTFOS on it and won’t update.

So my question is do I have to remove the above as to update them thus making them compatible with my goggles??? …,

It will need to be running the latest firmware to connect to the goggles intrgra

But it will then not connect to the goggles v2 or the older dji fpv 1 controller
