The basic approach is export and reimport.

Unfortunuately, Zope supports the export only for single
objects. This implies the need for intermediate steps:

  * Copy the complete structure

  * Delete everything, you do not like in the other environment

  * Export the structure

  * Import in destination

  * Copy everything at the final destination.
    This step may need to get automation support
    in case the structure is not flat and upper hierarchy
    nodes are already present at the destination.
