How to move sharepoint database to new db server.

Question

I am planning to move sharepoint database to new sql server cluster with dns name not thru the alias name.... what is the recommended way to do... any help is appreciated??? In open source documents... all are describing about how can we change the connection thru alias but we want to know about DNS approach... how can we move all database to new availability server and change the connection string...btw i m using SP 2016.
