I did this a few years ago, and while things did eventually work out, I made some mistakes that could have been really bad. Without going into too many details, just make sure that the place you are moving to is 100% done and the deal is sealed. Whether it is a home purchase, rental agreement, whatever. In my case, I packed up nearly everything we owned into a moving truck and drove it across the country about a week before the closing on the house. The closing needed to be in person and for family reasons, it wasn't possible for both my and I to both fly there and do the closing, so we just moved before hand. Well, the bank decided to pull some shady shit at the last minute after telling us everything was completely confirmed and we almost didn't get the house. We ended up staying in someone's basement for over a week while I did everything I could to salvage the deal.
Anyway, don't be me, get everything settled before you move.
