1. A computer-implemented method for performing server virtual machine image migration and dependent server virtual machine image discovery in parallel, the computer-implemented method comprising:

  • responsive to a computer receiving a request to migrate a server virtual machine image that performs a workload to a client device via a network, starting, by the computer, migration of the server virtual machine image to the client device via the network and, in parallel in real-time during execution of the migration, continuously discovering, by the computer, an identity of a set of dependent server virtual machine images corresponding to the server virtual machine image being migrated to the client device to increase performance of the client device by decreasing server migration time;

    responsive to the computer discovering the identity of the set of dependent server virtual machine images, generating, by the computer, a server migration pattern of the discovered set of dependent server virtual machine images for the workload;

    calculating, by the computer, a level of risk corresponding to migrating each dependent server virtual machine image of the discovered set of dependent server virtual machine images to the client device based on the server migration pattern of the discovered set of dependent server virtual machine images for the workload;

    calculating, by the computer, a score for each dependent server virtual machine image based on the calculated level of risk corresponding to migrating each of the dependent server virtual machine images to the client device;

    ranking, by the computer, each of the dependent server virtual machine images in a prioritized server migration list based on the calculated score for each particular dependent server virtual machine image, the workload, and criticality in performance of the workload by each particular dependent server virtual machine image to prioritize migration execution; and

    migrating, by the computer, the dependent server virtual machine images in a ranked priority order of the prioritized server migration list for each of the dependent server virtual machine images to the client device via the network to execute the workload.
