Abstract: A method and apparatus for the dynamic determination of migration data is described herein. In one embodiment, a process can be provided to search user data in a first system for migration data without requiring user interaction. The search of user data can be based on a blacklist. The blacklist can include one or more folders which should not be searched for migration data or one or more files which should not be included in the migration data. A search of system data for migration data can be performed without requiring user interaction. The search of system data can be based on a whitelist. The whitelist can include one or more file types.

Abstract: A method and apparatus for the data migration between disparate data structures is described herein. In one embodiment, a process is provided to determine information associated with one or more users in a first data structure which may be used to create an account in a second data structure for each of the one or more users in the first data structure. A portion of a first data structure to copy to a second data structure may be determined based on a search of the first data structure in its entirety. A structured view of a mail database associated with at least one of a plurality of mail applications in the first data structure may be created. The structured view may be configured to receive data from each of the plurality of mail applications. A portion of the mail database with the structured view may be streamed to the second data structure and may be used by the second data structure to create one or more files.
