i would like to mention here that having a careless host move your sites can be awful. we were moved by a host that failed to pay attention a few years ago. they have a good reputation and we had no dsl at the time so we couldn't do it... in some sections, our new server didn't have anything past 2 folders deep. when we went live, it was a disaster - we were permanantly blacklisted from several big tgps and link lists and in the long run, lost over $100,000 over the years.

so be careful who you host with. a good host makes all the difference!
