摘要

A list of subscribers to be moved from a set of existing equipment elements to a set of new equipment elements is determined. If a network management system for managing the set of new equipment elements is capable of supporting logical provisioning of subscribers before the set of new equipment elements are placed into service, then the set of new equipment elements for the list of subscribers is preprovisioned, subscriber connections to the set of new equipment elements are installed, and the set of new equipment elements in the communications network is installed; otherwise, subscriber connections to the set of new equipment elements are installed, the set of new equipment elements is installed into the communications network, the set of new equipment elements are placed into service, and the set of new equipment elements are provisioned for the list of subscribers. Subscriber connections to the set of existing equipment elements are removed.
