   > My only goal here would be to make sure that we don't support 2 different 
upgrade paths.
   
   Thanks for this clarification, that makes sense to me. Having a single 
upgrade path makes it easier to rationalize about any issues that come up for 
an update (we don't have to think about "Oh does X happen when it's 1 to 3 
directly or something else". It's a single path and so in case of any issues it 
must be at some specific point in the path). 
   
   I think I'm overall good with that, as long as we can keep the combinatorics 
to a minimum for testing. Which I think your strategy is as good as it gets?
