Change document structure

I am trying to change document type structure. ie.
Old::CommissionCDoc ==> New_Structure::subFolder::CommissionCDoc

After cut and paste the document type to new location, I cannot save having error message, “broker cannot delete 1 document type …” Is there any way I can do this? I am very tired of this problem.
Thanks - Keon

Have you tried stopping the adapters before saving? I have seen this message many times and if I turn off any adapter that has this event in its permissions and then try to save, it will save.
