(Newbie) Changing URL question

Hey All,

I have a ghost site on Digital Ocean and change the sites URL. I have managed to change the URL and get all the redirects working!

My question is now that I have the NEW URL set up, is it safe to change the OLD URL’s DNS records on NameCheap to point to some other place and remove the OLD URL from Digital Ocean? Sorry if this is obvious, but I don’t want to F things up now that I have it finally working…
