Hey guys,
Can't seem to find anything on this but then again I haven't gone through all the results that come up on the mailing list search either.
We moved from BB server to a Hobbit server a while ago but it was on the same box so there was no issue there. We are shuffling some old hardware around and decided to give our hobbit server some more grunt and
also
add some other odd apps on it. We'll want to progrssively move the
hosts
over to the new server so the clients are cool, just update the ip in windows ones, and the ip and hostname in the nix ones
As for the server I'm assuming I can just copy the data dir over for the host I'm moving. I cannot imagine there being anything server specific in any of the status messages or graphs ?
Watch out if you are changing OS/filesystem at all. Existing RRD files will need to be exported and imported rather copied if this is the case (I had to do this for a small-ish migration from Solaris x86
to Solaris Sparc).
So action plan would be, shut down client on XYZ, define it in bb-hosts file on NEWHOBBIT, has it out in the OLDHOBBIT bb-hosts file, copy appropriate data folders from OLDHOBBIT to NEWHOBBIT (update ownership if need be), update ip addy and hostname in XYZ client settings, start client XYZ, be happy :)
Any flaws in this thinking or suggestions of easier way even though I cannot imagine one can you please let me know
Thanks
Allan

Hmm ok I hadnt thought about that as I don't understand the inner workings of RRD etc. We're moving from a Pentium Pro 200 box on Redhat 7.2 to a Dual Athlon MP System on Redhat 9 (why RH9 you ask, its the ONLY supported OS for another application thats going on there and if we
hit any problems if its not RH9 they will not help us, poverty I know)
If I do a uname -m they both say i686, uname -p one says unknown other says athlon. Should this be an issue ? Also if they are different enough
will the graphs just not work or be corrupted or not update ? Can someone please assist me in how to import/export the rrd files then as I
have never done that before. Been looking in the rrd docs but still not entirely sure what I need/want.
The proxy idea sounds good although I don't know if its going to be warranted in this case as we don't have a huge number of hosts to deal with.
Thanks for the feedback guys
Allan

As the systems are both Linux, are same-endian (i686). and same FS (ext3?), I can only surmise that you should be able to just copy the RRD files.
If they are not compatible then the updates will fail as rrdtool will not be able to read the existing format.
As far as actually converting them goes, I kind of did it on the fly so don't have any useful scripts to pass on :-) It's pretty easy and the RRDTOOL website does provide examples (http://rrdtool.trexle.net/doc/rrddump.en.html)
