Ah, dang, bugger not having the -u option.  I wonder if ...
newer version of program that has -u option would be backwards compatible
and not break stuff?  Maybe something someone can - or has - tested
(e.g. on a virtual machine or whatever) ... or ... maybe just easier
:-) ... to wait 'till upgraded and that -u option is available.
It is present on the mailman version 1:2.1.18-2+deb8u1 on what's presently
Debian oldstable.  Not sure at what point/version that option was added.

$ dpkg -S /usr/lib/mailman/bin/fix_url.py /usr/lib/mailman/bin/withlist
mailman: /usr/lib/mailman/bin/fix_url.py
mailman: /usr/lib/mailman/bin/withlist
$ echo $(lsb_release -d; uname -m); dpkg -l mailman |
> awk '{if(($1=="ii")&&($2=="mailman"))print $2,$3;}'

I'm sure one *could* do the inter-host migration method ... for
inter-host migration, ... but that's significantly more
pain/work/complexity to do it that way.  And ... "of course",
sysadmins are "lazy" ... or more properly known as efficient!  :-)
Prefer to accomplish *more*, with less work/effort.  I (and many) call
that efficient.  So, sometimes (actually, a bit surprising often),
the answer is "just wait, then it will be easier" (or moot, or ...).

No request for actions are intended to be implied by ... :-)
