According to one aspect of the present disclosure, a method and technique for verifying data structure consistency across computing environments includes computing a first signature for a data structure of an application subject to checkpointing corresponding to a first computing environment residing on a server computer. A second signature for the data structure of the application corresponding to a second computing environment residing on a client computer is computed. The first and second signatures are compared to determine whether a change to the data structure exists. Responsive to a lack of change to the data structure based on the comparison, a mobility operation is enabled for the application between the server computer and the client computer.
