Abstract
A virtual machine (VM) is migrated from a first data center that includes a data store for handling input/output operations (IOs) of the VM to a second data center that includes a proxy configured with connection information to connect to the data store to enable the proxy to handle IOs in place of the data store. The method of migrating includes installing a first redirection filter in the first data center to redirect IOs from the first VM, which are directed to the data store, to the proxy, migrating a memory state of the first VM to a second VM in the second data center, installing a second redirection filter in the second data center to redirect IOs from the second VM, which are directed to the data store, to the proxy, and after the migration has completed, deactivating the first VM and powering on the second VM.
