I'm having a hard time not rolling on the floor laughing at this
discussion. If 7.2.1 is your standard of comparison, any of the later
branches are super stable ...
A more serious point is that 7.2.x to 8.x is a big jump in terms of
behavior; there were a lot of not-so-compatible changes in between.
Porting their application code first to 7.4 and then to 8.1 might be a
good plan in terms of not dealing with too many things at once.
I don't suggest moving their production databases twice, just divvying
up the work of testing and updating their applications.
