text: *Figure 5-23 Content Manager OnDemand for i migration policy hierarchy*
  
  When the migration policy is created, a corresponding storage set is created for the Content 
  Manager OnDemand instance with which the migration policy is associated. The storage set 
  is displayed in a listing of storage sets by using the Content Manager OnDemand 
  Administrator Client but it can only be viewed. No updates can be made to existing storage 
  sets, and no new storage sets can be added by using the Content Manager OnDemand 
  Administrator Client. Storage sets in the Content Manager OnDemand for i system can be 
  created and modified only by using IBM Navigator for i migration policies. 
  
  **5.4.2 Application group storage management**
  
  The application group storage management settings (Figure 5-24 on page 127) determine 
  how long report data and indexes are kept in cache storage before they expire. All documents 
  in the application group are loaded on the media that is part of the storage set to which the 
  application group is assigned. All documents in the application group migrate according to the 
  rules that are defined for the application group’s migration policy. When the application group 
  is defined, choices are made concerning how soon data is migrated to archive storage after 
  the report load is completed.
