Welcome to TN!
Can't offer any advice on that side of the state but I would like to recommend for you to look into a "Lifetime License" IF the state of Ms offers one before you move yourself and your family!!

Tn offers one and at the time would have cost me $1200, I did not purchase mine when I moved to Mo thinking they would not honor it....boy was I wrong and kick myself every time I think about it.
I have been paying $407 for NR TN license (all inclusive) for the last 10 years now so that $1200 would have been a wash after 3 years.

Just something I like to mention as I don't want others to make the same mistake (if your state offers a lifetime license) I did if you are like myself and go back home to visit family and hunt/fish. I only hunt/fish in TN and that just adds to the misery
