Then you need to backup your Boinc folder with a archive program

Please be precise when giving advice like this. Backing up your BOINC folder won't do any good. That's where the program files of BOINC reside.

You will need to backup the BOINC DATA directory.
Default places:

Windows 98/SE/ME: C:\Windows\All Users\BOINC\ or C:\Windows\Profiles\All Users\BOINC\ (*)
Windows 2000/XP: C:\Documents and Settings\All Users\Application Data\BOINC\ (*)
Windows Vista/Windows 7: C:\ProgramData\BOINC\ (*)
Linux: wherever you unpack it/BOINC/
Macintosh OS X: /Library/Applications Support/BOINC/

(*) This directory may well be hidden, so either put the path to it directly into Windows Explorer, or instruct Windows Explorer to show hidden files and folders.

The path to the BOINC Data directory shows in the messages when you start up BOINC Manager. Although there is a bug in BOINC, when you use Scandinavian characters (ö or ø) in the directory name, that it won't show it in BOINC Manager/Messages.

This was posted by Ghost in Lunatics forum, maybe it will help you...

No it's not necessary to clear out your cache before using the installer, but it is the safest
Here's the best way to apply the new build without running your cache down:

Ensure that the plan class and version numbers match the following pairing
Version 608 and plan class Cuda
Version 609 and plan class Cuda23
Version 610 and plan class Fermi_Cuda
If you have different plan class/version number pairing to the above you should run your cache down before proceeding as running the installer will trash your entire cache
Set Boinc to Netwok Suspended, and suspend all tasks. Then stop Boinc,at this stage I always take a backup of my entire Boinc Directory.
Now run the installer, start boinc and enable 1 or 2 tasks if they run fine enable the rest of the tasks and enable the network again
If they crash out you can always restore your entire boinc directory and try again

The installer will move all your old applications to a folder within the seti project folder so you won't lose these

Thanks.

So there is no way to change wu file names to match new install?

No it's about the app_info file and if you have the correct <plan_class> in place. If you installed the previous lunatics program you should be good to go... I think...

Thanks.

First exit Boinc. Then you need to backup your Boinc folder with a archive program like 7-zip. Then unplug your Internet connection, or disable the net card driver. Install the update and start Boinc to see if all works, if not then exit Boinc and restore the backup.

Crunchers,

There are several threads that refer to backing up files in case a fermi install is the wrong number (ie. 8,9,10) and discards all of your current GPU wu's. What is the best way to mass file name change, how is it done, and what specifics need to be changed?

Thanks,

Russ
