Thanks for the advice.

Well, actually one instance already has its own members and the other
also has other members.
So copy and paste portal_memberdata and acl_users does not solve this issue.

I should have said that how I can merge members between two plone instances.

Is password stored under acl_users since it could not be fetched from

If I can manage to merge members (maybe users?) then I can relate
memberdata based on member ids later on.
