Need to change the EV server name to CNAME alias

Dear All,

During a health assessment of an EV environment we came to know that the EV server is configured with the server name directly instead of using the CNAME alias as per the best practice. Now we also have a task to prepare the DR for thier servers and I nwat to get CNAME alias working before we do that. Is there any documented process to achieve this?

Thanks
