Migration policies move content files from one storage area to another, based on the rules (conditions) defined in the policy. Files are selected for migration based on format, content size, or date criteria. The target storage area of a migration policy can be a file store or a retention store (EMC Centera or NetApp SnapLock).

Migration policies are jobs that execute the MIGRATE_CONTENT administration method. The conditions are stored as job arguments. A Content Storage Services (CSS) license is required to create content migration jobs. CSS is enabled using a license key when Content Server is installed or when the Server Configuration Program is used to update the server installation.
