In a customizable data migration method and system, when a migration program is launched, it queries a system server for entity-level and user-level policies. The migration program then creates a customized interface to the user, where the entity-level and user-level polices are applied with hierarchical priorities. In this manner, flexibility is provided in the data migration process. The end user is allowed to maintain a personality on a given user system and to transfer this personality along with the company specified data. This increases the uptime of the user by reducing the re-customization time when the user is cascaded to a new user system.
