* copy the gameserver folder (to have 2 unique folders)
* copy the mysql\data\my to mysql\data\my2
* configure the new server with ip that you added as a second ip(keep database IP unchanged)
* configure new server to use my2 database, change server name(don't forget to edit both npc and msg server config files)
* add new server to account server (account.ini - just copy whole [Account1] section and rename it to [Account2], change Servername, optionaly login and password)
run one account server( it will handle both servers from now on)
* first msg, npc
* second msg, npc
if you will get error about msgserver already running, tell me, I will need to look at it.
