Abstract: Techniques for migration of a source protected virtual machine from a source platform to a destination platform are descried. A method of an aspect includes enforcing that bundles of state, of a first protected virtual machine (VM), received at a second platform over a stream, during an in-order phase of a migration of the first protected VM from a first platform to the second platform, are imported to a second protected VM of the second platform, in a same order that they were exported from the first protected VM. Receiving a marker over the stream marking an end of the in-order phase. Determining that all bundles of state exported from the first protected VM prior to export of the marker have been imported to the second protected VM. Starting an out-of-order phase of the migration based on the determination that said all bundles of the state exported have been imported.
