6. A machine system for migrating personality of a computing environment from a source machine platform to a target machine platform, said source machine platform and said target machine platform both having Common Information Model objects extracted on a Common Information Model-based system management infrastructure, the machine system comprising: a database recording migration rules of Common Information Model objects between a plurality of platforms; a migration rule extracting means for extracting from the database the migration rules of Common Information Model objects between said source machine platform and said target machine platform; a Common Information Model object extracting means for extracting Common Information Model objects related to said personality of the computing environment from said source machine platform according to the migration rules extracted by the migration rule extracting means, and for extracting from the target machine platform Common Information Model objects corresponding to the extracted Common Information Model objects of the source machine platform according to the extracted migration rules; a migration task producing means for generating the migration tasks to be executed on the extracted Common Information Model objects of the target machine platform according to the extracted migration rules; a migration task executing means for executing the generated migration task by the migration task producing means on the extracted Common Information Model objects of the target machine platform; a storage device comprising an instruction causing a processor to issue a migration request by a user, wherein the source machine platform and the target machine platform involved in the migration as well as the user data are specified in the migration request; and a double-face UI (user interface) navigating means for, when an application on the target machine platform is invoked, generating a translucent UI on the UI of the application, said translucent UI being identical to the UI of the corresponding application on the source machine platform which has similar functions with those of the application on the target machine platform.
11. The system according to claim 6 , further comprising a migration request processing means for processing the migration request of a user.
