When you upgrade from ODEX Professional to ODEX Enterprise you will probably want to import your existing ODEX Professional configuration into ODEX Enterprise.
This will be done the first time you run the ODEX Administrator application (part of ODEX Enterprise). You will be asked if this is a fresh install or an upgrade.
If you select the "Upgrade from ODEX Professional" option, then all of your existing settings will be copied across from ODEX Professional to ODEX Enterprise.
