I think you could find out sooner than that - just copy an rrd over to
the new system and try to dump it:

     rrdtool dump datafile.rrd

If you get XML, it's probably all good.  If it complains, you need to
do the export at the original host and import it on the new host.  I
just copied an rrd over from a Sparc system to an x86 system, and
rrdtool dump tells me:

   *** glibc detected *** double free or corruption (out): 0x0804a170 ***
   Abort

whereas doing the same with a locally-created rrd I get a stream of
xml.  Likewise, going back to the original system I can dump the
original file just fine.
