I have recently gone through a painful attempted upgrade process from 3.1 on FC3 to 4.5 on Mac OS X.

The FC3 server was old and had hardware problems.

Essentially, it doesn't seem possible to do this upgrade path. I tried but in the end simply decided to install a fresh 4.5 on the Xserve.

I want to be able to recover the contacts/address book and calendar data from the 3.1 installation files.

Where are these stored?

Or would I have to set up temporary FC3 box, get my 3.1 installation running on that, and use the SOAP API to get at these? I would prefer not to, if there is a simpler way to do this.
