A method and system for workload migration across a hybrid network is provided. The method and system are directed to migrating a workload to a cloud by transferring the workload computing processes to the cloud, streaming workload data as necessary to execute the workload processes in the cloud, transferring the remaining workload data in a background process to cloud storage, and then completing migration by switching the primary data source of the workload computing processes to the cloud storage. In another aspect, a method and system are directed to migrating on-premises storage associated with a virtual machine to the cloud to be stored and executed in association with containerized applications. Additionally, techniques for full detach and partial detach of containerized applications are provided.
