When an application running at a first data center needs to be migrated to a different data center, the first data center is able to automatically locate an appropriate target data center from among multiple other data centers for receiving the migration of the application. The first data center ensures that a specified level of performance of the application will be maintained following migration of the application by preparing a migration request document that specifies network requirements, server requirements and storage requirements for the application. A targeted data center that is a candidate for receiving migration of the application receives the specified requirements and uses a performance index and other analysis to determine whether its hardware, software and other configurations are capable of meeting the specified requirements. The results of the determination are sent back to the requesting data center, which then decides if migration will be carried out.
