This issue typically comes up when moving data from a 32bit to a 64bit system. The commands are very easy to work with for one file, but with many files and multiple directories (subdirectories) it can be cumbersome. I found this post in a forum and found it extremely useful and powerful.

This should be a foo.sh file and you should run it in /usr/share/app/data where the files are within data or below that. It will convert and rename the file from rrd to xml. Transfer the data over to the new system and run the same command (either no argument or look at the bottom for ‘help’).
#!/bin/sh
ECHO="echo -e"
rrdump ()
{
for rrd in `find . -type f -name "*.rrd"`
do
xml=`echo $rrd | sed 's/.rrd//g'`
rrdtool dump $rrd > $xml.xml
rm $rrd
done
}
xmlimport ()
{
for xml in `find . -type f -name "*.xml"`
do
rrd=`echo $xml | sed 's/.xml//g'`
rrdtool restore $xml $rrd.rrd
rm $xml
done
}
case "$1" in
dump)
rrdump
;;
import)
xmlimport
;;
*)
$ECHO "$0 takes one of two arguments\n"
$ECHO "$0 dump -- dumps contents to xml\n"
$ECHO "$0 import -- imports xml files to rrd\n"
