A few reasons to reapply.
1) Law school is extremely competitive. Don't assume that you will be do well enough to transfer. You should go to a school that you actually want to graduate from. If you happen to do well enough to transfer, fantastic. It is extremely difficult to do well enough to land yourself in the top 1/4 of the class and have a significant chance at transferring.
2) Doing well is no guarantee that you will be able to transfer. A friend of mine is at Cooley. They are in the top 5% of their class. So far, they have been rejected from Hastings, U of M, UCLA, and Wash U. St. Louis (a VERY transfer friendly school). The only acceptance she has received is from Michigan State. Being top 5% requires a huge effort, and if the only reward for that effort is a T4 to T3 transfer, then the investment/risk is huge for a small payoff. Not saying this is what will happen to you, but there is certainly a possibility that it could happen to you, even if you are at the top of your class.
3) Studying/retaking the LSAT is a lot less work that 2 semesters of law school + all the work it requires to send out transfer applications, statements of interest in those schools, letters of rec from current profs, etc. Basically, either way you go, you will be reapplying. The difference is, you will have less stress if you simply retake the LSAT because you won't have the burden of students loans, class, and cut-throat competition to worry about.
4) Appalachian School of Law does not have a good reputation. The only thing most people know about this school is this that there was a horrible shooting on campus a few years ago. http://timlambert.org/guns/appalachian/nd/tackle/165.html
My advice is that unless they offered you a major scholarship, thus reducing the risk of long term debt without significant job opportunities, you should retake the LSAT. Even a marginal increase of 5 points could put you into the T2 range where you can have a higher job placement opportunity and better environment.
