Moving RRDs from one version of rrdtool to another

Wow. Yet again I figure something out immediately after I click *send*. Looks like I needed to use "dump" instead of "xport". xport was the option in the older version, which I thought I had.  :)

I truss'd the command and don't see any reason for it to fail. the last thing that happens before the failure is checking my timezone:

Meh.

Hi,

I had the same problem, the cause is that Sparc and Intel/PC hardware
have different endianess.

What I did is what you suggest, dump, copy, restore. The trick is you
have to restore on the target host. Installing two versions of rrdtool
on the solaris box won't do.
