My work PC is about to be replaced. I'd like to keep the partially completed WUs so that they can complete on the new PC. Last time I tried this - by copying across the folders - they were deleted as "unknown" on the other PC. Is there a way that they can be "saved" so that they can complete on the new PC?

You can only do this when you move the complete BOINC directory (or Data directory in case of BOINC 6) with all sub-directories to the new PC, while the new PC must be using the same operating system platform and have the same CPU manufacturer as the old PC had.

So... Can do:
Windows 2000 -> Windows XP
Intel P4 -> Intel Core2

Can't do:
Windows XP -> Linux
Intel -> AMD

It also depends on which projects you are attached to, if they are updated enough to allow the above. In any case, all your work is registered to the PC that downloaded it, that same PC should upload it. The PC is registered at the project under the hostID. When you change CPU or OS, you will get a brand new hostID, to which all that work isn't registered, so it won't upload/report it to that one. Lost time and work.

If the OSes and CPUs don't match your best bet is to run out your cache on the present PC and if that's not possible, to abort all the work you have in progress and start anew on the other system.

After you moved the directory, you should of course install BOINC on the new system, pointing to the directory you just moved to install BOINC in.

Thanks. The problem is that the old PC will be "recycled" for another user, and BOINC will certainly be removed at this time. So I can't wait until they've finished then upload them. So I guess the WUs might as well be aborted when the PC goes away.

Sorry that was me. I used an old account!
