Migration Overview
The differences in Cisco Secure ACS 5.x and Cisco ISE platforms, operating systems, databases, and information models, mandate a migration application that reads data from Cisco Secure ACS and creates the corresponding data in Cisco ISE. The migration application is a utility that Cisco provides to extract the configuration from Cisco Secure ACS and import it to Cisco ISE. The migration administrator can view the current progress as well as the detailed logs related to the ACS configuration during the entire migration process for troubleshooting purposes. Error messages are displayed for objects, attributes, and policies that are not migrated. After migration, we strongly recommend you to verify the accuracy of the migrated configurations. Please ensure that you understand the semantics and structure of the policy sets in Cisco ISE and verify them against the access policies in Cisco Secure ACS.
Note |
It is possible to leverage the migration application to extract data from Cisco Secure ACS even before installing Cisco ISE. In this manner, the migration application can be leveraged to determine the readiness for migration from Cisco Secure ACS to Cisco ISE. |
