[hobbit] Moved Hobbit to a new server, and now the Graphs have disappeared.

When I run this on the old server it outputs the xml file, rather than creating the file -- It is rrdtool 1.2.11 - The version on the new server is 1.2.30

Should I be dumping this to a file? Ie rrdtool dump tcp.conn.rrd > tcp.conn.xml

Hi Brian,

you use "rrdtool dump <filename>.rrd <filename>.xml" to dump the 
contents of the RRD <filename>.rrd to the XML file <filename>.xml. 
Execute this for all RRDs on the old machine, and copy the .xml-files to 
the new one.
Then, with "rrdtool restore <filename>.xml <filename>.rrd" rebuild the 
RRDs from the XMLs on the new machine.
