[Mailman-Users] Migrating Mailman to New Server (Same Domain)

There are different versions of python, so I will stick to only copying the lists and archives directories.  What about copying the data directory?  I read that this was important too.

That rsync should work if you want absolutely everything to be the same.
There could be issues if the whole environment is not the same. E.g. if Mailman was configured --with-python=/usr/bin/python2.6 and the only Python on the new server is Python 2.7.

Also, there can be considerations if E.g. the user number for the 'mailman' user is different on the new server, but rsync usually handles that, at least if running as root on both ends.

That's why we suggest building a working Mailman on the new server and just moving lists and archives.

Aside: the 'r' in '-avr' is redundant as it is implied by '-a'.
