I am working on an upgrade from SC 7.2 -> SC 9.1.1. First I used the Express Migration Tool to upgrade from 7.2 -> 9.0. Then I did a manual upgrade from 9.0 -> 9.1.1. Now I am seeing the following errors in the log file and I don't really understand what these mean. Can anyone help me understand what this error is and how I can fix it?
