For a logical explanation of topology differences, sets of topology rules are imported into the Rule Engine in the form of XML files. These XML files are located in the <BASEDIR>\smarts\conf\tcat directory, for example, C:\InCharge\IP\smarts\conf\tcat\IP_9.2.0_TopoRules.xml. The IP_9.2.0_TopoRules.xml file contains rules for the 9.2 server.
Do not modify the .xml files. These files are populated with rules and the tool will produce undesired results if these files are changed.
