How is MySQL upgrade happening in the LTS 14.04 -> 16.04 upgrade?

When doing the LTS upgrade from 14.04 to 16.04, how is MySQL updated, is a it just an in-place upgrade from Mysql 5.5 to 5.7? Or is there something fancier going on behind the scenes, like a logical dump that's dumped and loaded back in?


The reason I ask is I'm trying to do a clean install of 16.04 and I'm wondering how to migrate my MySQL data... (all the MySQL docs say do 5.5 -> 5.6 -> 5.7 but just wondering if its necessary)
