Migrating from GroupJive?

I am currently running a Kunena / Community Builder site that focuses heavily on GroupJive for CB, for user-managed communities. Basically, an Admin creates a group and hands it to a User, that User becomes the group's Admin, and handles all membership, moderation, etc, without the Joomla Admin needing to be involved.

Is this something that EasySocial can handle / replicate? Can it migrate from CB / GJ to ES, without a loss of either data, or user memberships & permissions?

Thank you!
