Sorry, no it's not that easy :-(

FreeRADIUS 1.x and 2.x are *not* configuration compatible. Your best bet 
is to start with the default out of the box 2.x config and make only 
incremental changes based on a thorough understanding of how the server 
works and what your requirements are. It's best to keep your config 
files under source code control. If something breaks you can go back to 
a working configuration, review history, etc.

Once that's working do everyone a favor unlike your predecessor and 
document what you did and how it works (at the moment it sounds like 
you're going to have to unravel what your predecessor did, only then can 
you move forward).
