You can install the Deprecated Server Behaviors extension in DW CC to get the Database functionality back:
You don't have to swap back and forth.
However, if you do have both versions installed on the same system, you can install the extensions in both DW versions and it will count as only one activation.
The license terms allow you to install the extensions on 2 computers. If you have multiple versions of DW installed on one computer, you can install the extension in all of them
