Moving things between ecosystems
There are a few ways to move something from one ecosystem to another, and they do different things.
An ownership transfer moves one object, such as a persona or a project, to a new owner. The workspaces pages describe it.
An ecosystem move carries the data across. It never moves the records that say who a person is.
A customer transfer moves one person: their account, and the ecosystems they own. It moves one person at a time, and a preview checks a whole batch before anything moves.
A membership adds a person to an ecosystem, or removes them, without moving anyone. A removed membership is kept as a record of its removal, and a person's membership in the hub itself cannot be removed.
