Next Generation Network NGN is a centric converged network aims to provide a multitude of services over a single integrated network infrastructure, rather than multiple separated and overlay networks, as have existed for decades. The deployment of NGN have brought unique challenges in how to deploy and implement the migration phases to NGN with the best scheme, lowest cost , fastest speed and minimum risks. Operators plan to migrate to NGN to simplify their networks, introduce new NGN services, and reduce CAPEX and OPEX. Network simplification is the most important step to widely and easily introduce NGN services. Operators are searching for a smooth, reliable, and cost-effective migration solutions without services impacts. Replacements the transit and the tandem layers will reduce the network complexity and facilitate the deploying of NGN services, however it is the most difficult step in implementation. This paper will present a detailed practical solutions and plans to smoothly migrate the tandem and toll offices to NGN. A detail cut over process with the necessary Precautions will be outlined. The results of migration the transit and tandem layers of Yemen Telecom legacy network will also be presented.
