I have been working on pulling the data from the older server.
Since the server was last online Mojang started allowing anyone to change their username. Mojang now uses a unique identifier (UUID) to identify your account. This identifier follows you through your names changes.
Before UUID was added all data by your character was referenced by your username. If you changed your username you no longer have a rank, a town, and permissions.
I was able to map our database of thousands of players to their new identifiers. I was also able to bring over the original ranks. Your rank has been moved to a prestige in front of your name.
The star in front on my name is signifies that i was an admin and my white names shows that i am a new player.
