Abstract: An example method of migrating a virtualized computing instance between source and destination virtualized computing systems includes executing a first migration workflow in the source virtualized computing system, where a host computer executing the virtualized computing instance is a source host in the first migration workflow and a first mobility agent simulates a destination host in the first migration workflow. The method further includes executing a second migration workflow in the destination virtualized computing system, where a second mobility agent in the destination virtualized computing system simulates a source host in the second migration workflow and a host computer in the destination virtualized computing system is a destination host in the second migration workflow. The method further includes transferring, during execution of the first and second migration workflows, migration data including the virtualized computing instance between the first mobility agent and the second mobility agent over a network.

Abstract: A method for migrating a virtual machine (VM) includes establishing a first connection to a first cloud computing system executing a first VM, and establishing a second connection to a second cloud computing system managed by a second cloud provider, which is different form the first cloud provider. The method further includes instantiating a second VM designated as a destination VM in the second cloud computing system, and installing a migration agent on each of the first VM and the second VM. The migration agents execute a migration process of the first VM to the second VM by (1) iteratively copying guest data from the first VM to the second VM until a switchover criteria of the migration operation is met, and (2) copying a remainder of guest data from the first VM to the second VM when the switchover criteria is met.

Abstract: A method of migrating a virtual machine (VM) having a virtual disk from a source data center to a destination data center includes generating a snapshot of the VM to create a base disk and a delta disk in which writes to the virtual disk subsequent to the snapshot are recorded, and copying the base disk to a destination data store. The method further includes, in response to a request to migrate the VM, preparing a migration specification at the source and transmitting the migration specification to the destination, the migration specification including a VM identifier and a current content ID of the base disk, and determining that a content ID of the copied base disk matches the current content ID of the base disk included in the migration specification and updating the migration specification to indicate that the base disk does not need to be migrated.
