When copying Amanda tapes to a larger media, I read all parts with dd
as long as the capacity of the new tape is reached and then I write
these parts to the new tape with dd.

In order to recover you should position the tape manually (with mt),
and you must disable amrecover_check_label in amanda.conf (otherwise
amrecovr would rewind and see the wrong tape label at the beginning of
the tape.
