Cisco ISE incorporated Cisco ACS (Cisco Secure Access Control System) between ISE releases 2.0 and 2.3. Cisco ACS was a network access policy platform that provided authentication, authorization, and accounting (AAA) services for network devices and users. Cisco ACS was discontinued in 2017 and replaced by Cisco ISE, which offers more advanced features and capabilities for identity-based network access control. Cisco ISE provides a migration tool that allows customers to migrate their data and configurations from Cisco ACS to Cisco ISE. The migration tool supports Cisco ACS versions 5.5, 5.6, 5.7, and 5.8 and Cisco ISE versions 2.0, 2.1, 2.2, and 2.3.

 = A business case is an option that will help build your customers platform during the discovery phase. A business case is a document that outlines the rationale, objectives, benefits, costs, risks, and alternatives of a proposed project or solution. A business case helps to justify the investment and align the stakeholders on the value proposition of the project or solution12.

During the discovery phase, the goal is to understand the problem that needs to be solved, the user needs and context, the constraints and opportunities, and the underlying policy intent. A business case can help to achieve this goal by providing a clear and concise summary of the problem statement, the desired outcomes, the potential solutions, and the evaluation criteria34. A business case can also help to communicate the vision and scope of the project or solution to the customers and other stakeholders, and to secure their buy-in and support56.

A business case is not the same as a POV report, a detailed design, a high-level design, or a PO. A POV report is a document that summarizes the findings and recommendations from a proof of value (POV) exercise, which is a short-term trial of a solution to demonstrate its feasibility and benefits7. A detailed design is a document that specifies the technical and functional requirements, architecture, and configuration of a solution8. A high-level design is a document that provides an overview of the solution, such as the main components, interfaces, and interactions9. A PO is a purchase order, which is a document that authorizes a purchase transaction between a buyer and a seller.
