cPanel will be a complication if the old server is not also cPanel.

As long as both Mailman versions are 2.1.x and the target version is as
new or newer than the source version and the source version uses the
standard MemberAdaptor (i.e. no custom member database), this is
normally completely straightforward. It may be complicated if going from
non-cPanel to cPanel.

You need to stop Mailman on the old server or at least be sure that your
lists are 'quiet'. You need to get all the lists/*/config.pck files and
all the archives/private/*.mbox/*.mbox files from the old server and
move them to the new server.
The cPanel complication is that the *'s above are listnames and in a
non-cPanel installation, the listname of the listx at example.com list is
'listx', but in cPanel it is 'listx_example.com', so those directories
and files will need to be placed on the cPanel machine with their cPanel
names. I think this is the only complication.
After moving the files, you should run Mailman's bin/check_perms to fix
any permission issues, run fix_url and run 'bin/arch --wipe LISTNAME'
using the cPanel listnames for each list to rebuild the pipermail
archive on the new host.
I'm not sure exactly how to run fix_url in a cPanel installation or if
it will even work, and I'm not sure it's necessary if the domain names
aren't changing. I'm guessing for listx at example.com, you could run
bin/withlist -l -r fix_url listx_example.com -u example.com
but this may leave the list with an incorrect host_name. Maybe it's best
to not run it, do one list as a test and if things are OK, just proceed.
