How to copy Publication and Active Content in DOC1 Designer 5.6

Product Feature: Work Center
Assuming you want complete separation between the original publication and ACs, and their respective clones, then this is the only way which is available within the repository in Designer 5.x.

Depending on what the user wants to accomplish, the alternative options for complete separation of the ACs and publications are:
1. Export a snapshot and import that into a clean repository. This is only viable if you have the possibility of working in separate repositories. If you were to import the modified items back into the same repository, they would update their respective original copies.
2. Use Designer 6.x or later which contains the Branching functionality. However this also assumes a separate development strand, or an eventual remerging for the branched content.
