#1 Moving WU's

I see that there are a few projects that have humungous work units, Climate Prediction for one estimates 300 hours or so.
My question...say I need to remove a machine that is 50% of the way through the WU, is it possible to transfer the unit, and the crunched data to another machine?
This might be best asked on a BOINC forum rather than a team forum, but I reckon there are enough peeps here who know what they are doing to be able to answer

It certainly used to be possible, although I've not tried it with the current version of Boinc Manager, just by copying the whole of the Boinc directory via a pendrive. Be warned though, I've lost a few CPDN models from them crashing on the new machine.

As a last resort I'll try that then, hope it wont come up though
Cheers

Moving the entire Boinc account (Program Files) does work. I've done it many times. The only problem may be different versions of the Boinc client. Just make sure that the versions are the same OR just install a new version AFTER you do the move. The client should recognise the work out there and just resume like nothing happened. Some projects care about what machine their work is downloaded to but most don't.
It DOES NOT work for x64 operating systems though.

As I just mentioned elsewhere - I move CPDN installations around quite a bit and have rarely had problems. (although it hurt when I lost six weeks of work...
)
I find that it works best if BOINC isn't actually installed on the machines (with old version anyway - I think the new versions do an autoinstall if they start and don't detect the registry component or something
)
You do have to be careful to run 'net stop boinc' before trying to move things around though as sometimes it doesn't fully... ...dissengage?
