Changing Intranet Url and configuring AAM

Hello,

I already extended my web application to Intranet, and now I have a requirement to change the url again. 

So, what are the steps I need to follow in CA and IIS? 

Do I just need to create another DNS record, and replace it in AAM? And also I need to edit the binding? This is Production, so I need to know of doing it best way. 

Thanks

John
