Hi Ricardo
I'd take any opportunity to do a clean install rather than an upgraded one.
If you want to minimise gaps in your graphs, it would be best to minimise the cut-over time, and make "IP address change" be the cutover event. I'd build a second server, probably using the Terabithia repo, use rsync to replicate the RRD files and history, on command, and test the new server before cutover. I'd probably update one or two clients with two IP addresses in XYMSERVERS, as part of my testing.
My only concern with a VM is that VMware apparently introduces time jitter, so if you're doing anything time-sensitive (eg using Smokeping, testing NTP services) you may see artefacts in your graphs.
Cheers Jeremy

We have an old instance running 4.3.24 under RHEL6 and in an old physical server.
Would like a complete upgrade including moving he server to our VM cluster. What would you recommend? P2V, OS upgrade to RHEL7, and Xymon upgrade? Or complete new installation including possibly using Terabithia's RPMs and migrating logs and such? Since we have several local clients reporting back, it'll have to be the same original IP address. Test new server, down old one and change IP address?
Welcome any/all suggestions. TIA.
