Actually, there's a pretty easy way to transfer your WU's to the new SETIQ from the old version...
Just install the new version in a different directory than the old one, point the new Q's proxy address to the old Q, set the buffer settings to a really high number (high enough to get all of the work from the old Q), set the new Q to listen on a different port than the old one for now, then configure one client connect to the new Q to get it going, and download all of the WU's from there and you're set. 😀
Of course, you'll then have to reset the proxy and buffer size settings to what you want them to be on a permanent basis, but you can then have the new Q 'listen' on the same address and port as the old one was using so that you don't have to reconfigure any of your clients except for the one used to start the Q for the first time.
