So I was going through the available online manuals but didn't find anything about the upgrade process from the MK3S with MMU2S to a MK3S+ with MMU2S. I guess I'd just have to kind of smash the 2 guides together and make it work, but I guess my main concern is just the length of the PTFE tube for extruder. Does this change at all?

The MMU2S is compatible with both MK3S and MK3S+, there is no update to the MMU2S.

When I receive the ordered MK3S to MK3S+ kit in January, the only needed upgrade to the MK3S my MMU2S is unchanged.

Have a look at my designs on Thingiverse or on PrusaPrinters ;)...

Are you sure? Checking the parts in GitHub suggests there are new Mk3s+ parts for the MMU.

I don’t have an MMU so can’t be sure, but there are def. parts labelled MMU that are not part of the Mk3/s to Mk3s+ upgrade kit.

The guide is here, but it seems you do have to upgrade the extruder to Mk3S+ first, at least the first part up to and before the idler and FS top.

If you have the very first MMU2 (as I did) there has been updates to it and I recently updated the MMU2 with the new parts and got it to work. I don't think there is updates following the MK3S->MK3S+ upgrade.

Edit: The new MMU2S parts on the MK3S+ is properly for the moved filament IR sensor...
