Moving RRDs from one version of rrdtool to another

[Charles Jones]

I wish to move a Hobbit monitor that has been running for quite some 
time on a Solaris platform, to a new Linux server that I setup. I did 
not want to lose the history for the hosts so I copied the data 
directory to the new host, but it seems the rrd files are not compatible 
as I have missing graph links.  I checked the permissions and they are okay.

Hmm I checked rrdtool versions and here's what I found:
Solaris: rrdtool version 1.0.49
Linux: rrdtool version 1.2.18-1

* Now I am assuming that the problem is the difference in the rrdtool 
versions.  I don't really want to roll back to an older version on the 
linux box.
 * After some research it looks like rrdtool has an option to dump an 
rrd to XML. You can then import that XML to another rrdtool version. I 
will try that and report if it works or not.

Note: I'm not asking a specific question in this post...I'm mostly just 
"thinking out loud" in case my problem and resolution helps others who 
search the mailing list.
