Calculating the amount of time that a VirtaMove migration will take is a factor of application size and complexity, as well as network speed and bandwidth availability between the source and destination servers. The more network latency, the longer a migration will take. Many hops on a network, a low transfer rate, or high packets loss could reduce performance and increase migration time. VirtaMove includes a tool that will test a network for possible latency.
The amount of time that VirtaMove migration will take also depends on operational flexibility, use of migration best practices, and resources assigned to a migration.
