Congratulation on your first move! My first step is always to talk to your transportation office. They will help you establish a moving timeline so you can determine, when you will move, when you schedule the packers and movers, and can find somewhere to live in your new location. Once you establish a timeline you can start to plan out all of the details.
http://www.move.mil/home.htm is a very helpful site where you can manage your move online and watch some helpful informational videos to hopefully make your move smoother! Thanks so much for posting and asking a question, please let me know how your move is going and if you have any other questions! Good Luck!
