If instead a staged application migration is chosen, where only a percentage of applications are migrated to the network, then the new overlay network will need to communicate with the legacy network and be required to operate in a brownfield setup.

A brownfield setup normally means applications are migrated in stages to the new platform, as opposed to all in one go, which builds confidence in the new network and new technology associated with that network.
