Oh boy! It's been over six years since I did it, and I retired three years 
ago, so I'm going from a very rusty memory. (Anyone else want to step in 
here??)

As I remember it, I set up an ssh key on the new server for the xymon id on 
the old server and ran the process from the old server.

Essentially you run rrddump on each and every rrd and redirect the output to a 
file. Ship the file to the new server and run rrdrestore with the new file 
input from stdin. You will need to manually recreate the directory structure 
on the new server to match the old.

I did the entire process with a script run on the old server for each 
subdirectory under each host, IIRC - it's been  bit too long and the memory is 
fuzzy (I don't even have rrdtool installed on this system - I'm watching this 
list out of a sense of nostalgia :-) ).


Anyway - man rrddump, man rrdrestore, and man rrdtool should get you started, 
then it's just a bit of trial & error to build and test the scripts.
