Copy all the torrent files to a location, then copy all the data files to another.
Set the default Azureus torrent directory to the first place, and the default DL directory to the second.
Then open the torrent files in Azureus, it should find the data and start seeding.
Should that fail, then open the torrent files one by one, make sure it starts, so that the files are created on disk, but then immediately stop it. Copy the real data files over the newly created data files and force a re-check. Then start seeding.
