beware of the dumped dataformat. I had to sed ‘,’ to ‘.’ in the dumped .xml-files to get right data on the target

Thanks for these scripts.

You might want to check for existing .rrd files for the xml files before restoring them though, so that you do not convert wrong files.
This might happen when copying data (rrd files) from another host, where the domain setup does not match (hostname vs. hostname.domain in filenames).

[...] If your old and new server are not the same architecture, then you need to perform a dump and restore process on the RRD files rather than just copying them across, because the binary data contained in the files is different between 32-bit and 64-bit systems. In our case we decided to just stick with a regular x86 setup for the new box, so I can’t comment on how well this works, but I found the following article which looks like it should work just fine: munin: migration from a 32bit to a 64bit host.

Hi Halbert,
The scripts should work for a 64 to a 32 bit migration. But I did not try it myself.

Hello,
I didn’t realize you needed to dump your rrd files if you were migrating from a 32bit to a 64bit server. I can only assume a similar process is necessary if you go in the opposite direction, from 64 bit to a 32 bit server.

In that case, would your export and import scripts work?

Thanks
