I don’t see why not; over ten years ago the OpenVZ vm code had a way to rsync a container across the network; syncing everything; then only the pages that had changed since the start of sync; then the final pages that had changed in the last few seconds. There was a tiny delay to pause the container on the old and start on the new host; but I am sure that this could be reduced further.
