  Understanding the difference between Enhanced Retention Management and IBM Enterprise 
  Records is critical to choosing the correct solution: 
  
  (cid:2) Enhanced Retention Management provides for the lockdown of documents and prevents 
  expiration. 
  
  (cid:2) Enterprise Records declares documents as records that immediately become part of a 
  
  corporate file plan. Enterprise Records notifies the Content Manager OnDemand 
  repository when it reaches its event-based expiration. This action passes control to 
  Content Manager OnDemand to delete the document unless Enhanced Retention 
  Management is also enabled for the same document. If Enhanced Retention Management 
  is also managing the document, it waits until the hold is released before the document is 
  eligible for deletion. 
  
  When you use Enhanced Retention Management or Enterprise Records, Content Manager 
  OnDemand must be in complete control of expiration processing. Therefore, if you use IBM 
  Tivoli Storage Manager or object access method (OAM), you must disable the ability for either 
  of these storage managers to expire data. Also, you can use Enhanced Retention 
  Management and FileNet P8 Content Federation Services for Content Manager OnDemand 
  only against application groups that have an expiration type of LOAD. For those application 
  groups that have expiration types of DOCUMENT, SEGMENT, or STORAGE MANAGER, 
  utilities are available to convert those application groups to LOAD. We recommend that you 
  engage IBM Lab Services to provide these services.
