Usually the heavy lifting is done by windows migration tool that's built in. Sometimes it's grabbing a few files manually. I don't know what the nerd in the IT office has done beforehand. New machine gets restored from the migration tool file, files manually saved are replaced, and then I call office-nerd to beam down special software and some final things. I meet more of the "moving things place to place" and "square peg-square hole, round peg-round hole" kind of qualifications stuff for them. There's usually one or two people from the team doing something via computer in the IT office though I am unsure what.
