[Mailman-Users] trouble seeing migrated list on admin page

[Peter]

I have migrated a list from an old installation (2.1.5) to a new machine 
(running 2.1.8).  It appears that the move was successful since I can access 
its page at:

http://mailman.domain.com/mailman/admin/<listname>

But it does not show up on the main admin page:

http://mailman.domain.com/mailman/admin

This is the procedure I used for the move:

cd /var/spool/mailman/lists
cp -pr $OLD_MAILMAN/lists/<listname> .
withlist -l -r fix_url <listname>
cd ../archives/private
cp -rp $OLD_MAILMAN/archives/private/<listname>.mbox/ .
cleanarch -n < <listname>.mbox/<listname>.mbox
cleanarch < <listname>.mbox/<listname>.mbox > tmp
cp tmp <listname>.mbox/<listname>.mbox
arch --wipe <listname>

There are no errors in mailman/logs.

Thanks,

Pedro
