In Cisco Unity, how do I remove the Cisco Unity attributes from the Exchange AD accounts to import Unity users after Unity is re-installed?

[TCC_2]

Core Issue

The Cisco Unity server is going to be rebuilt from scratch, so the Exchange server and the mailstore need to be rolled back to their state prior to the Unity installation. All the Unity attributes, schema changes and other settings must be removed from the Exchange server.

Resolution

For procedures to roll back an Exchange server and remove all the Cisco Unity installed attributes, refer to these documents:

• Importing and Creating Subscribers In Cisco Unity    
  
• White Papers for Cisco Unity Version 4.0    
  
• Unity System Administration Guide

How is the above document helpful and at rev.2? Here's a list of 20 white papers, the answer is somewhere in there, possibly?
