There are at least two ways to do this. The messages are in Mailman's
data/ directory as files with names like heldmsg-LIST-nnn.ext where LIST
is the listname, nnn is a sequence number and ext is either 'pck' if
mm_cfg.HOLD_MESSAGES_AS_PICKLES is True (the default) or 'txt' if it is

One way would be to extract the messages from the heldmsg-*.pck files
(or just use them as if they're .txt) and queue them to the correct
list's incoming queue with Mailman's bin/inject command. The tricky part
here is if the heldmsg-* files are pickles, extracting the message
requires a separate step, but something like

for f in `ls data/heldmsg-englishlist-*.pck; do
  bin/show_qfiles $f | bin/inject -l frenchlist
  rm $f

should work, or just

for f in `ls data/heldmsg-englishlist-*.msg; do
  bin/inject -l frenchlist $f
  rm $f

for the .msg case.

Another way is to use the script at
<http://www.msapiro.net/scripts/hold_again>. This requires renaming all
the heldmsg-englishlist-* files to heldmsg-frenchlist-*, while
preserving the extension an then running

 /path/to/hold_again -l frenchlist

Yes, with either method.

The Approved: password will be stripped.

You will need to turn off require_explicit_destination or add the
english list to acceptable_aliases or the messages will be held by the
french list.

After doing either method, the admindb page for the english list will
show a bunch of "Message with id nnn was lost." messages the first time
it is visited. This is harmless.
