Switching Servers

We just converted from 3.0 to 4.0 a couple of weeks ago. Shortly we
will be upgrading our Vantage server to a new box. What would be the
best way to move everything to the new machine? Load 3, upgrade to 4,
restore db from backup, etc...? The new box will totally replace the
old one (same name, ip etc). Anybody done this? Thanks for any help.
