You may want to try UdmUtil::CopyObjectHierarchy.

overwritesononly one child

Hello,
   I have already tried FAMM::LSC::Create(FamMSC). It creates a new,
but empty object under FamMSC. What I would like to have is to have a
clone/copy of the matched child object, FamLSC, put under the parent.
  If the only way to obtain a non-empty child object is to use
newChild = child.CreateInstance(parent), then is there a way to detach
the new child objects from the original child, so that I can later
delete the original child safely, without also deleting the new ones.
  Regards,

Gurkan
