Introduction


 

The Cisco ACS 3.x appliances and software have been around for many years. The deployment base of that is still staggering. There has been a keen interest  in providing a migration path and guidelines for achieving successful migration to a later more stable solution .This document sheds some light on the migration path and available options when migration from Cisco ACS 3.x to Cisco ACS 4.x etc. The migration process is quite straight forward as the majority of the ACS 3.x deployment is running on compatible operating systems namely windows platform and compatible database system. Being a compatible OS and Database the migration of user database and ACS configuration settings is complete.
