Please do the following steps before applying the hotfix.
1. Disable V9 flow export in the router. 2. Click the License Management Link in the NetFlow Analyzer web console and delete the specific router. (This will not delete the historical data collected for that router)
1. Shutdown NetFlow Analyzer service. 2. Execute \"updatemanager.bat\"/updatemanager.sh file present under the <NetFlow_Home>/bin directory. 3. Select the hotfix ppm in the upgrade window and proceed with install. 4. Start NetFlow Analyzer. 5. Enable v9 in the Router.
