Move Munin on new server with old data

Question

I have to move my Munin instance on new server. I've installed from package (Debian) Munin 2.x. All was fine, but ... I copied /var/lib/munin to new server. But after updating munin overwrite old data and i have empty graph :( Could you tell me why? And how i can save old data?

I tried rrdtool dump/restore too. It was the same :(

Thank you for answer and help.

Br,

Is your munin recording only for the single server? Is the hostname the same? — EightBitTony, Oct 22 '12 at 07:17

What is the version of rrd databases ? The last munin want 0003 and you may need to convert them. Check with a file the version.

You may check your logs : you will maybe see something about the owner or something else.

To convert :

#!/bin/bash
SOURCE="/var/lib/munin/DOMAIN/"
cd $SOURCE
for FILE in *rrd
do 
  echo $FILE
  rrdtool dump $FILE > /tmp/$FILE.xml
  NEW=`basename $FILE .xml`
  rm $SOURCE/$NEW
  rrdtool restore /tmp/$FILE.xml $SOURCE/$NEW
  chown munin:munin $SOURCE/$NEW
done
rm /tmp/*.xml
