Since the --rrd-dump option would only benefit 32 to 64 bit migrations
performed after an upgrade to 2.3.2, I'm posting the scripts that I plan
to use for our migration. You may need to modify some of the initial
variables if your zenoss install is not the same as mine. They are
fairly straight-forward scripts:
* dump-zenoss-rrd - Dumps the rrd database files to .xml files in a
directory named /tmp/rrddump. Tar up /tmp/rrddump and copy it to
your 64-bit server.
* restore-zenoss-rrd - After zenrestore has been run, this script
restores data from the /tmp/rrddump directory into Zenoss
installation.
I'll post updated copies after my migration if there are any adjustments
made.

One of the things I'm toying with is the idea to add an --rrd-dump option to
zenbackup that backups RRD files in XML format instead of native integer
format. But I don't know if its really worth the effort.
Would be a good thing, I you add that function I will create a trac request to
commit that back to zenoss.
I follow the forums for a while and I notice this is a question which comes
quite often...
