The preferred method is to move the lists/listname/* files over, rather
than moving the list configuration and membership as you did.

I think you can still move the new lists/listname/config.pck and
config.pck.last files aside (don't delete them yet in case something
goes wrong), and move in the old lists/listname/config.db files. If
this works OK, you will have the list config and membership and member
options from the old lists. If not, you can move the config.pck files
back. There is really no other convenient way to move member options.

Note: You cannot leave the new config.pck files in the lists/listname/
directory or the old config.db files you move in will be ignored.
