How to change server in SAP B1 8.8

Dear All,

I have a problem in using SAP B1 8.8. I have 2 separated server which is one is contain license server and the other server contain database company. My client doesn't want the company database in one server with license server. In SAP B1 2007 that my client used before, this is not a problem. But now, in SAP B1 8.8, it's become a problem because SAP remove "CHANGE SERVER" button in modul change company. I tried to click in the server list but the server that appear is License Server only. I can't find Database Server.

So, How can i choose the database server ?

Pls help
