I moved the config.db file from a test list to the new server.  I logged in to the web interface and all the members were there and the settings looked good.  Moving the archives over and rebuilding them even worked.  However, if I try to run dumpdb on the newly migrated list I get this error:

NameError: global name 'DumperSwitchboard' is not defined

Although there are other posts in the mailman-users archives where people saw this problem; there was no resolution.  So it seems that even though the list appears to function properly and the web intercase works, something is not quite right with the config.db file and Mailman version 2.1.9.  It makes me a little nervous to run the migrated lists in production knowing that I can never run dumpdb and I don't know what else might be broken.  I think I will go with my original plan of pre-creating each list on the new server, importing the list member's email addresses and manually setting up the list.  With 150 lists, I think I can do it in a week.

I'd like to try the transfer of config data programatically using withlist but I can't seem to find any comprehensive documentation on the use this command.   There are lots of posts in the archives and on google concerning specific uses of the command but no comprehensive usage instructions in one place.   I'll keep searching.
