In my company, the hardware of mail server will be updated ,i have to export/import the large data, but don't know how to move the lists and archives, who can help me?
I have referred to some FAQ,but failed. eg. http://wiki.list.org/display/DOC/How+do+I+move+a+list+to+a+different+server-Mailman+installation.
Mailman's version is 2.1.8
I highly recommend you ask your question on the Mailman-users list:
More people read there regularly and can help you out!
You'll need to provide some more information, though: what went wrong?
