1. A method comprising 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 CIM objects extracted on a CIM-based system management infrastructure, said step of migrating comprising the steps of: a. providing in a database migration rules of CIM objects between a plurality of platforms; b. extracting from the database the migration rules of CIM objects between said source machine platform and said target machine platform; c. extracting CIM objects related to said personality of the computing environment from said source machine platform according to the extracted migration rules; d. extracting from the target machine platform CIM objects corresponding to the extracted CIM objects of the source machine platform according to the extracted migration rules; e. generating migration tasks to be executed on the extracted CIM objects of the target machine platform according to the extracted migration rules; and f. executing the generated migration tasks on the extracted CIM objects of the target machine platform.
