Today I need to migrate cacti from old machine to blade. I have hit the problem This RRD was created on other architecture. Old system was 64bit and new one was existing 32bit system. RRD’s must be converted.
It can be done by exporting to xml
rrdtool dump rrd_on_old_host.rrd > rrd_on_old_host_dumped.xml
transfering to new host (eg. scp) and restoring with
rrdtool restore rrd_on_old_host_dumped.xml rrd_on_new_host.rrd
