I have been moving to a new PC over the last three months, and have been running BOINC on both the old and new PCs during this time. I am now forced to shut the old PC down. How do I move the work done and work in progress on the old PC to the new PC so that it is not lost.

There is a link to a thread on moving models towards the bottom of this README post. It\'s basically the same procedure as a back-up and restore.

So, I just move the files from the BOINC folder on the old PC into the BOINC folder on the new PC? What about the files that have the same name? For example, both BOINC folders contain the file \"account_climateprediction.net.xml.\" Which do I keep?

No. You won\'t be able to merge the two installations. Copy the old installation (i.e. the whole BOINC folder) to the new machine as a separate installation (e.g. C:\\BOINC_OLD_PC). Then choose which one to run (probably the shortest); when that\'s finished, run the other one.

By \"choose which one to run\", I mean download and re-install the BOINC software to the path of the installation you want to run (e.g. C:\\BOINC_OLD_PC, or C:\\Program Files\\BOINC); the download page for CPDN is here. BOINC is very good at recognising that an existing installation has data in it, and will run it without having to re-attach to the project or download any new data. You can even install a newer version of BOINC, if you want - that works really well, too.

The reason for re-installing BOINC is that all the icons and system settings then point to the right place.

[Edit: By the way, as far as I know, you can only move models between PCs that have the same executable: in practice this means between PCs with the same operating system (i.e. Mac/Darwin to Mac/Darwin, Linux to Linux, Windows to Windows) - so the recommended procedure will only work between your Windows PCs.]

That seems to have worked ... and I have the latest, greatest version of BOINC. Now I assume that when I\'ve finished with the old PC work, I just install it in the new PC folder and proceed as usual.

Yes. And delete the folder that contains the remnants of the finished work.

You\'ll end up with a number of host entries in your CPDN account. Some of these should be capable of being merged, to reduce the clutter.

Hi Dean

Your climate model will probably run faster on the new computer. When a model is speeded up a lot, this can sometimes cause an unusual type of model crash before the model completes. If you take regular backups of the complete contents of the boinc folder it means that if this problem does occur, you\'ll be able to rescue the model and finish it.

There\'s a post about this in the moving your model section of the Running the model README.
