Not that I'm aware of, but just do what I used to do. Go into uTorrent and change the default download location to (for example) F:\Torrents instead of E:\Torrents. That way anything new will end up on the new drive, but all the old stuff will still be seeding/stored on the old drive. Sure you might have to check two drives now to find a file, but since they'll be separated by when they were downloaded that shouldn't be too difficult.
If you're looking to do something beyond that, I'm not sure what it is you're asking then.
