We are trying to deploy service reference to Production.

I am trying to follow the steps in the below website to change the URL of WSDL:

http://blogs.msdn.com/b/floditt/archive/2009/02/09/deploying-service-references-with-dynamics-ax-2009.aspx 

Will the URL of WSDL revert back to non-Prod URL when we have the next full layer deployment?
If this is the case, should we deploy this service reference to another layer such that it won't get overwritten?

I appreicate for you input.
