It is normally not recommended to copy the data directory. In any case, I *think* when you start mailman the last_mailman_version file will be overwritten, and this file is only used to determine whether to run bin/update when you install a new version.

If the file is not overwritten it would be good to restore  the original data.

Mailman upgrades config.pck files as necessary on the fly. It doesn't downgrade, but that won't be a problem here.
