Anyone experience any issues when updating or have any suggestions to avoid loosing work, especially with these LONG sulphur models.

tia.

Should be working without problems, just replace the boinc binary with the new one and start it.

If you want to be safe, stop BOINC and make a backup copy of the complete boinc dir.

Yeap, it's more easy to upgrade in Linux. just stop Boinc, change the binary, and restart it.
If it doesn't work, you just put the old binary back ;o)
