Change CRM server name in MSCRM_Config

I've tried to change the name of a CRM server for testing purposes and from my research I found that in the MSCRM_CONFIG database, the server still shows as the old server.

here is the command that I used to find out the server:

SELECT Name FROM MSCRM_CONFIG.dbo.Server

How would I change the server name inside the MSCRM_CONFIG database to show the new server?
 My SQL knowledge is very limited.


Thank you!
