I don't have a ton of knowledge about DNS so I want to be as cautious as possible before I pull the trigger on a re-point.
I am doing a simple migration of a website from one server to another. During downtime I want to do the DNS switch to the new server. If something goes wrong and I switch the DNS back immediately, what could potentially go wrong here? Could the DNS get mucked up in any way?
I will have the TTL set to 5 minutes on each server prior to making this change occur.
