You should probably do some reading and learn what you do and don’t need to change.
With respect to DL and tags, it’s whatever the state says. Not hard to find.
Real world, it’s not a huge deal. In fact the only real world risk is a random traffic stop literally for out of state tags, and you having a reason to decidedly NOT wanting to get pulled over!
And the only time that is likely is if you’re frequenting the same small town and the same Barney gets a hunch you should have in state plates.
Having moved about 10times in the last 25 years, I learned to not worry about it.
Sometimes I would have been wrong by one states laws or the other anyway.
Bottom line not a big deal.
And what would you change on a passport?
