Hi,
Is it possible move one teamspeak server to another gametracker account ? Because Im new owner of one portal and I dont want delete old statistic etc also I dont have acces to account where is it now added.

You can re-claim a server in the exact same manner as if it was the first time being claimed. If you have any troubles doing so, please let me know.

Ok i claim one of my teamspeak server naplno.sk:9988 but if I try add another one what is added on another gametreacker account it say : A server with this ip/query_port already exists in the GameTracker database. Ip of teamspeak is naplno.sk:9987 . It is possible move all statistic and everything to my new account ?

You've already claimed the server http://www.gametracker.com/server_info/85.248.229.179:9988/

I'm not quite sure what you think you're missing. Please explain.
