301 Redirects against DNS change: is it ever safe to kill 301 redirects and update DNS for a subdomain?

I have a site running in a subdomain that has been transferred to a new server and a new domain name. To save search loans, I know that 301 redirects are the right way to handle migration. (The marketing department talks about 301 redirects that I've never heard of.)

From a technical point of view, I do not understand how long you have to support redirection. Can someone explain this? It seems that additional and unnecessary loading on the server supports redirection unlimited. Do you end up dropping it or changing the DNS after the search engines no longer link to the previous site?

301 "moves forever", so theoretically search engines and browsers that have a link in their bookmarks should switch to the new URL. But I would not argue that everyone is doing this. So, I agree with ceejayoz, it is wise to keep the old URL forever.

(Remember that the URL is not only stored in search engines, you can find them in many places, even on paper. Therefore, the URLs never die. Think twice before you publish the URL, you can never remember it. )
