New PC...

I've just put together a new PC that I'll be using as my main playout. My question is this; do I need to re-analyze the entire music / video collection when moving over to the new PC?
The file structure will still be the same on the new PC. They're both stored (D:\MUSIC and then various subfolders, but exactly the same).
Also, if I don't need to re-analyze, what else do I need to copy to the new PC?
