I've made a copy of everything onto another external HD with a different disk name. All I need to do is to get iTunes to point to the new drive, with the music files in the same places within the folder hierarchy.  I've been unsuccessful at getting iTunes to make the switch.  (I tried editing the library files with a hex editor and that's a bust.)

Maybe something like this:

tell application id "com.apple.iTunes" -- iTunes.app
	repeat with i from 1 to count of tracks of playlist 1
		set oldLocation to location of track i of playlist 1
		set newLocation to my modLocation(oldLocation)
		set location of track 1 of playlist 1 to newLocation
	end repeat
end tell

on modLocation(oldLocation)
	set oldPath to oldLocation as text
	set saveTID to AppleScript's text item delimiters
	set AppleScript's text item delimiters to {":"}
	set oldPath to text from text item 2 to character -1 of oldPath
	set AppleScript's text item delimiters to saveTID
	log oldPath
	return alias (newDiskName & ":" & oldPath)
end modLocation

It assumes they're still in the old place as well, which might not be the case. But it might give you some ideas.
