Abstract:
A method of migrating legacy software applications to new product architectures comprising the steps of:developing a migration plan identifying software functions to be migrated from pre-existing software to a new product architecture;evaluating each functional request to determine whether that function is part of the migration plan;executing those functional requests determined not to be part of the migration plan as received;evaluating a functional request determined to be part of the migration plan to determine whether the pre-existing software or the new software is in control;executing those functional requests determined to be part of the migration plan for which the pre-existing software is determined to be in control as requested, then translating the request to the new software and executing the functional request on the new software;translating those functional requests determined to be part of the migration plan for which the new software is determined to be in control and executing the functional request on the new software;evaluating those functional requests determined to be part of the migration plan for which the new software is determined to be in control to determine whether the pre-existing software has been shut off; andexecuting those original functional requests determined to be part of the migration plan for which the new software is determined to be in control and the pre-existing software is determined not to have been shut off.
