Initiation

The user manually initiates the start of migration following the setup phase. This ensures that new writes are directed to the target vault before the source vault listing phase begins, and gives the user the opportunity to allow any in-progress writes to complete. Immediately following the setup phase, the Start Migration button will be grayed-out for several minutes. This is to ensure that the configuration information has propagated to all of the devices in the system when the migration is started.
