Files to move to a new server?

I will be moving the existing system from a desktop PC to a Dell 1850
Server over the next week or so.

 
In order to preserve the current information, what files/directories do
I need to move to the new system?

What permissions do I need to worry about?

I want to keep the RRD history data for the graphs also.

 
I am running Xymon 4.3.0-0.beta2.  

Is there a newer version that I should be running?

 
Thanks,
