[hobbit] Problem converting 32 bit disk-rrd's to 64 bit

[Smith, Jim]

Is it just the disk graphs that are incorrect or is it all graphs?

Can't say I've ever seen this syndrome - but a suggestion - can you
temporarily install a more recent version of rrdtool on the old server
to use for export, so you do not have such a version disparity between
the two systems?  I can't speak to RRDtool 1.3, have only used up to
1.2.27 for Hobbit.
