The setup information file ".smw.json" is used to store information about the upgrade process and the setup independent of any active database connection.

The file stores information about the upgrade progress, the installation in general, and any other changes that might appear during the life-cycle of the extension. In cases where the file is no longer accessible, was manually changed, or removed, an error output will appear until the file is re-generated and contains required information.
