style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">My current hobbit 4.2.0 server,
running on HPUX 11v1 has served us well over the past almost three years, but
the old rp5400 with 2x540 Mhz PARISC chips, monitoring 435 hosts across 3
continents is starting to run out of steam and its time it be replaced.

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I just got two new HP DL380 G5
servers which we purchased to build out as new Xymon servers (one for prod and
one for DR). I am wondering what is currently the most stable
release of Xymon? I see 4.3.0-beta2 is the most recent. Would that
be the best to use for new production monitors? <o:p></o:p></SPAN></FONT></P>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Finally, I have seen comments about
people who have written scripts to transfer the data out of RRD files an old
server to their new server. Since I am migrating from HPUX to
RedHat, I gather that is my only option to migrate the RRD data.
Anyone out there willing to share their scripts which do this
migration? That would sure save me a lot of coding and testing
time.<o:p></o:p></SPAN></FONT></P>
