RRD-files are architecture-specific in format, so if you go from
e.g. a 32-bit system to 64-bit you will need to convert all of your
rrd-files.
If your Xymon server changes IP, then you'll need to reconfigure
all of the clients reporting to the server. Plus any firewall
changes that might incur.
Other that that, doing a new install on the new server and then
copying all of the data- and configuration-files across should work
fine.

we just migrated from Hobbit 4.2.0 running on Debian Lenny to Xymon
4.3.10 on a new machine with Debian Squeeze and had to dump and
restore a lot of rrd databases since there is also a Cacti
installation on the same server.
There was one gotcha that took us some time: the language variables on
the two machines were set to different values and our restored rrds
got mangled with wrong min/max values. To avoid this you can simply
set the LANG Variable when dumping and restoring. We used the
following commands:
on the old machine:
cd /var/lib/hobbit/rrd && for i in `find ./ -type f -name "*.rrd"`;do
LANG=C rrdtool dump "$i" "$i.xml";done
transfer the xml files to the new machine
on the new machine:
cd /var/lib/xymon/rrd && for i in `find ./ -type f -name "*.rrd.xml"`;
do LANG=C rrdtool restore "$i" ${i%.xml};done
Regards,
Peter
