My situation isn't quite there yet, but this is very close to my main
reason for wanting to do this type of migration..all of the big things
work and work well but there's too many little things that're not
fatally wrong right now but seem likely to turn into bigger issues down
the road and getting downtime to try to fix them just isn't going to

The method outlined by Mateusz Małek looks very interesting and worth
looking into..yes, definitely not trivial but doable.
