using Cloudberry Backup v3.0.2.122 on Mojave 10.14.6

With CB 2.x, I was unable to get my backup plan to include another user's home directory, even after changing the owner of the plan file to root. So I used the 'check for updates' option to update from 2.x to the version above. Now my /opt/local is empty. Cloudberry still runs, so the plan files must have been moved somewhere. Where can I find them now under 3.x ? I did check under /usr/local but no luck.
