I didn't have any trouble moving the graphs, and I made a similar leap in versions, but I stuck with the 32 bit architecture and didn't have any problems. I did have problems with my DR/Backup server, which is 64 bit, but recompiling and reinstalling rrd and Xymon fixed them. I didn't try to move the rrd files onto this machine. Since its my backup its getting all the same data that my main server is so its building its own graphs, if a true DR situation arose we could live without the graphs.

I recently moved to a new server. The way I did it was to install the newest Xymon release on the new server. Set up a Xymon proxy on the old server so it can feed both the old and new servers. Make sure the new installation is running right. Then use scp to move over all of the data directory. Turn off your old machine. If you have any proxies running anywhere you will have to point them to the new server after you have switched over, before you shutdown the old server. Same with any network tests you are running from your main server. That's about it, it went really smoothly for me. If you are running any network tests from your main server, be sure the firewalls are set up for the new server.

Thanks, Larry Barber

Our current Xymon server is running on a vmware vm. The powers-that-be want it to run on a physical machine. Unfortunately there is no V2P converter. So I've set up a new Linux box. Looking for the best way to migrate from old server to new one

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

Well, I shall endeavor to try this again by the end of the week and see if I can nail anything down. Knowing it should work is something. I'm migrating from Solaris 9 to Solaris 10 at the same time, but not sure if that should make any difference. I suppose there could be an RRDTool version difference at the same time or something? I'd assume both of them are 64-bit, as both Solaris definitely are.
