DNS Server Update question

[mcdwg]

I sold a site and now I am getting ready to transfer the site to him, I will be doing the uploading of the site.

My question is, do I update the new DNS servers before the files are uploaded or after.

Thank you

You change name servers after you've got the site properly working on the new server.
