I don't have them handy, but I got the header dumpdate warning, which
I guess is harmless.  Then I would get hundreds of "expected next file
A found B" error.  Sometimes it would suddenly give me an abort [yn],
if you hit n, then you just get another abort [yn] until you give up.

I'll check out your link and give things a few more tries.  I figured
I must be doing something wrong since dump/restore is so highly
recommended as the best choice.

Thanks, Kevin.
