migration from 9.2.2 to 10.3.1: missed all mlists

[maumar]

Hello
we have migrated from 9.2.2 to 10.3.1; all went well, a part from mailinglits: none was migrated and, even worst, no error in the logs: is this a known bug?
How can I export mlists by old server and import them on the new one?

 

[maumar]

/usr/lib/mailman/bin/export.py -l lista -o /tmp/lista.xml

to export, then to import?
