Camera Updates for original URSA Mini

I own the original URSA Mini 4k. Since all of the current camera updates offered are specifically for the newer models, is it safe or even worth it for me to try and update my URSA Mini? I have not updated since the 4.2 version, so if I were to update, could I just go right for the most current version, or would it be safer to go up one at a time?

I just bought a new boxed Ursa Mini 4k from a company clearout so it had no updates whatsoever. The update app upgraded the firmware to the latest version without a hitch, I don't think there's anything to worry about.
