You should transfer the files a week before the old host's account expires, then ask them (if they are in control of the domain name) to change it to Surpass's servers. If you have control over the domain, then do it yourself. The reason for the week advance is that it gives you a buffer while the domain propagates. This will make the transfer totally seamless unless you have a lot of dynamic user-added content or something.
