Moving from Arkansas to New York State

And I'm wondering if there's anything I need to know. I'm not so concerned with cost or culture or anything like that, I'm more concerned with things I need to settle before I even move, like potentially insurance or the like. I've lived in this state my whole life, and have never even considered the prospect of moving, so this is all very new to me, and any help would be greatly appreciated.

For, I hope, obvious reasons, I'm not saying which city in particular I'm moving to, but I do have it decided as well as some employment and housing.

I would post this in another subreddit, but I can't seem to find any for this particular thing
