Hola! Few new to LP questions...

Hey fellow Moogaholics! I’ve had a MG-1, then Prodigy, then (and now) Rogue starting in '90, and have played them live and in studios as much as the respective bands could stand- My stepbrother recently swapped out his Korg MS2000 and ARP AXE for a LP, and LOVES it so much, I’ve decided to get one too- I really like the look of the Tribute, so I got one on Ebay- But the guy I bought it from has done NO OS upgrades- I don’t want to have to lug around the Rogue just for sample/hold and noise, so am interested in the upgrade- My question is, since this one’s still at 1.0, do I have to upgrade it first to 1.2, etc.,etc., before I go all the way to 2.0?
Here’s some of my pre LP stuff:

and my more “normal” act:

The V2.0 OS upgrade isn’t yet available for the Tribute. The current OS is 1.03c, found on the Moog web site. You can upgrade to 1.03c from any previous version.
