The obstacles to adopting new network technologies that enable new applications and services are reviewed and discussed. Technologies such as client-server and interconnection mechanisms enable the realization of new applications which are "nice to have." Making these new technologies as easy as possible to exploit and use is a key in adopting them. Obstacles such as cost and complexity of managing the changes have been proven to be two of the barriers to adopting these technologies. Additionally, ignoring the importance of the legacy systems and their associated applications services, and infrastructures as well as introducing a set of new technologies which may not work well with the older systems impedes the acceptance of these new technologies. A set of migration technologies and strategies must be developed to remove the obstacles and to accelerate the adoption of these new network technologies.
