Before the upgrade, you made a backup copy of your customized files, web.xml and pluginsvr_config.xml. The upgrade process installed new default versions of these files that you must replace with your customized versions.
Copy the backup customized AIML files to the $BMC_VIRTUAL_AGENT_HOME$\VirualAgentComponents\var\programd\aiml\ directory.
Note
Do over the aiml\ directory because version 8.1.01 includes a sample AIML file.
