Moving All Collaborators to New Workspace


We would like to reorganize our workspaces, combining 5 difference space under one umbrella workspace. However, how can we take our existing collaborators and their current permissions to that new umbrella space. Do we have to re-enter them all or is there a way to move them? (See example below, want to move Workspaces 01-07 into on umbrella Workspace O2 Implementations) Is this even possible?
