How does one upgrade the BOINC client (say from 4.05 to 4.09) without restarting the cp.net application from ts 0? Last time I put the BOINC client in a new directory and the application restarted all over again. Shall I simply stop the application, overwrite the BOINC client and restart it?

that should be all you need to do, it will run benchmarks but I went from 4.05 to 4.09 without restarting my CPDN work.

You can just replace the existing BOINC program file with the new version and restart it.

HOWEVER:

Be careful to do it with the SAME userid that has been executing the program up to that point. I made the mistake of running the new version from a different ID (root) than the one that had been running it up to that point...and it wiped all the progress up to that point and started over. No...I did not have a backup (dumb).

This happened with BOINC 4.05....it may have been changed in later versions of BOINC.....but I'm not game to try it and I don't have time to mess around with it anyway. It is likely permissions related....and not a bug.

I start boinc in my startup script.....so this was relevent. If you simply start it in a console manually and always from the same ID, then you won't have anything to worry about.
