Transitioning from SEP 1.x to 2.0

Smart meter deployments have steadily increased, with millions of meters installed. The ZigBee Alliance began an effort in 2006 to define a smart energy application profile based on interest from meter companies, utilities, and in-home device manufacturers. The effort resulted in the ZigBee Smart Energy Profile (SEP), released in 2008 as SEP 1.0. The Zigbee Alliance revised the application profile to SEP 1.1, then SEP 2.0. As a result of significant architectural changes and feature upgrades, SEP 2.0 is not backwards compatible with SEP 1.x.

This paper outlines the results of analyses of multiple SEP 1.x to SEP 2.0 migration scenarios, in the form of requirements and best practices to enable successful migrations and/or network coexistence.
