It appears that the new server is running 2.1.10 or later with the
"sibling lists" feature, and the old server from which the lists were
moved did not have this feature, so the lists did not have the
corresponding regular_exclude_lists and regular_include_lists

However, that doesn't explain what is happening, because the first time
the moved list is instantiated on the new server, Mailman should
detect that the list's data_version is less than the installation's
DATA_FILE_VERSION and update the list's attributes. So, the question
is why didn't this happen, or if it did, why weren't the
regular_exclude_lists and regular_include_lists attributes added?

Did the old installation have patches that increased it's
