Configuration files
These configuration files were modified or customized by you, by another user, or by an app. The modifications are incompatible with the recent macOS upgrade. The modified files are in the Configuration folder, organized in subfolders named for their original locations.
To restore any of the custom configurations, compare your modifications with the configuration changes made during the macOS upgrade and combine them when possible.
My question is how to restore because not aware of the configuration changes happened during OS upgrade. Can't open all migrated files after upgrade.
