Before you start converting the PPM database, perform a converter test run to identify possible problems.
Procedure
In the bin directory <PPM99_CLIENT_RUN>/bin of your PPM 9.9 installation, execute the following command:
runppmconverter -client <client> -user system -password <password> -check
If warnings occur during the converter test run (log output starting with W:) you can usually perform the conversion without taking any action.
