Parent and child relationships can be changed. Configuring permits child workspaces to be "reparented" to new parent workspaces. Reasons that you might want to reparent a workspace include the following:
To reorganize workspace hierarchies
To populate a new project hierarchy (new top-level workspace)
To move a feature into a new release
To apply a bug fix to multiple releases
