This week another long CPDN WU will complete. I have set BOINC not to download any new WUs automatically.

So, I think this is the perfect time to upgrade my BOINC client from 5.x to 6.x

My question: with no WU active, is it better to uninstall 5.x before installing 6.x, or is it the same to just upgrade 5.x to 6.x ?

P.S. (this is Windows XP)

You need to update to V6 OVER V5, so that the BOINC installer can find your old data files.

And DON\'T go beyond 6.2.19 for now, unless you want to live in interesting times. :)

Also, if you choose the Service install option, be aware that the Copy & Paste method of backups no longer works, due to permissions not being copied along with the folders & files. (It still works with 6.2.18)

Thank you for your reply and advice.

I did feel the need for some \"interesting times\", so I downloaded and installed 6.4.5. However, the first WU it downloaded crashed immediately, so I gave up on the interesting times and installed 6.2.19. The new WU now runs fine.
