ODS 11.0 to 11.1 is a minor ODS change, so no harm done. As a total safeguard I would have backed up the ODS 11.0 database under Fb 2.0.x before uninstalling - in case I needed to revert to v.2.0.x for some reason - but backing up and restoring is meant to be AOK when the major ODS version is the same and the path is upward. Going backwards is possible, but a little harder....
