Is it possible to over-ride DNS

[Jonas]

We're going to move a site from one server to another. The website is
using our SSL cert running on a 3rd server. 

When we change the DNS to point the domain name to the new server we
will run into problems if the DNS for the SSL server isn't pointing to
the new server immediately. 

Is it possible to enter the domain name in the host file or by some
other means make sure that the SSL server points to the new server when
the change occurs?
