Because you moved /usr/local/mailman while Mailman was running on the
old system so you moved the lock files.

OK

Unless you stopped Mailman in between, you now have two masters and
sets of qrunners running. This is bad. See
<http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq04.068.htp>
and stop all the Mailman processes as described there and then do
'bin/mailmanctl start' just once.


>The maiman daeman were up but both mailman and http://hostname/mailman/admin/ didn't work. Does anyone know how to resolve it?


Didn't work how? What happens when you post to a list? What happens
when you go to that URL?


>questions: Is the above moving method correct or not? Did we forget something else? Is there a better way to move mailman without re-compile it to another same hostname, IP address, and same OS system machine?


I would stop the MTA, web server, Mailman and all other services on the
source machine before moving the directories and files, but I would
prefer to actually install and test all the software on the new box
and then just move the list and archive data for Mailman.
