Scanner has a very good point. It would be much easier to bring down the old server, attach the storage from old server to new with the same paths, name the new server the same as the old, point aliases to the new server, and then basically do a DR operation to have EV configuration automatically configure the new server to be just like the old one. If you have to retire the old storage where the vault stores and indexes reside, then I suppose it's a bit of a wash either way.
The Admin Guide's section on recovery covers the restore procedures in very good detail, should you be curious about going that route.
