Typically, you only need to do this between major upgrades, like 8.2.x
to 8.3.y ... 8.3.x to 8.3.y doesn't require a dump/restore unless the
release notes state otherwise (this has only happened a few times, I
think there was a 8.0.1->8.0.N that required it due to a minor change
required by a bugfix)
