You didn't really need to rerun Orca, just moving the RRD files over to the new 
machine would have been sufficient.

Are you deleting or moving your RRD files?  That would cause the problem.  You 
do need the keep these around, because that are binary data stores of the data 
that orcallator or procallator gathers.

The only time you need the old source data files is if you delete the RRD data 
files or add a new plot definition to your Orca configuration file which would 
cause it to reload all the original data files.

Moving old data files out of the way will also speed Orca up.
