Topology Change Analysis Tool (TCAT)

The Topology Change Analysis Tool (TCAT) identifies the key topology differences between various versions of IP releases and provides logical explanations based on any feature changes or enhancements. TCAT helps you to identify changes to a set of objects, relationships, and attributes which are related to device certifications for IP Manager upgrades from 8.1.3, 8.1.4, 9.0, and 9.1 releases to 9.2.

Note:

Unexplained topology differences may be observed if you have not applied the latest patch for a release. This is because there may be certification changes between patch releases.
