I urgently need to rename hc database server

I have gone into an issue a need to rename the hc server who also are the mssql server for hc and its database.
What do i need to edit, files registry edits etc. is there anyone who have a idea of this?

Simply run RegisterServer.exe located at : C:\Program Files\Advanced Communications\HostingController\Applications and specify SQL Instance name as <machine_name> OR <machine_name>\SQLInstance. This would automatically change things in system registry too.

thanks for your answer, but hc fixed this issue for me
