First of all, thanks Oscar, for all the advice. I learnt a lot even though I didn't use much of what you suggested. =8P Here's what I did:
1. DWFBinderReRoute (within the existing app).
2. copied main & cover docs in other app.
3. in the other app, I updated the "FolderIDOS" fields.
4. DWFBinderConsolidate (in the other app).
The proper person was able to claim and reassign it in the new app. :-) Now, I'm making changes to the architect to make sure that the workflow works properly.
Thanks & have a good weekend!
