Abstract
A non-disruptive cancellation of a migration-based virtual machine (VM) upgrade uses a network swap workflow and may be performed without user involvement (e.g., without providing login credentials). A source machine and a target machine swap machine identities such that, for example, the target machine takes on the internet protocol (IP) address of the source machine and the source machine takes on the original IP address of the target machine. Upon a cancellation of the upgrade, the source machine and the target machine revert to their original machine identities, for example, by swapping machine identities again. In this manner, the target machine assumes the role of the source machine for the user if the upgrade is not canceled, and the source machine rapidly resumes its role for the user if there is a cancellation. Advantageously, fewer computing resources are required for this cancellation.
