Moving RRDs from one version of rrdtool to another

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.
