Upgrading Advice

[Steve Witt]

I've got a software development lab of about 100 Debian Linux machines 
(3.0 - woody) that I'm using cfengine to manage. I started with version 
2.1.1, which is what I'm using now. I didn't use the Debian package 
because I believe that the version in woody is pre-2.x.x. I'm feeling that 
2.1.1 is getting pretty old now and that I should keep up with the newer 
versions. The question I have is whether there have been any significant 
changes to the latest cfengine that might really mess up my configuration, 
or if I should expect a pretty transparent upgrade.
transparent.

I don't think I'm doing anything too fancy with cfengine. I copy some 
configuration files to the clients, copy a couple of scripts, and run 
them. Anyway, I'd appreciate any advice you'all might have.

Thanks...
