Hi Thomas!
You'll need to change the license file so that it will be VM only instead of UM.
If you want to change UM to VMO you need to create new Exchange/AD accounts for the users, and do a backup with DIRT in order to keep all the user accounts, greetings, etc. Otherwise you
can loose all the settings and that means you need to start from scratch.
Use DIRT to backup all your data, please refer to this link to see which data is stored and which is not:

Once you backup the current configuration, reinstall Unity with the "Voice Mail only" option, restore your current configuration and add the new Exchange/AD accounts for mail only. Once the installation is complete you can
restore the Unity info from the DIRT backup.
Please refer to thes documents too:
