Municipal Library of Ústí nad Orlicí (Městská knihovna Ústí nad Orlicí)
The library’s 2015 annual report says it moved to the open-source Koha integrated library system in May 2015, replacing Clavius, and transferred its data into Koha. This is an explicitly documented migration. The report also identifies a VuFind catalogue interface, but this entry records only the documented Koha migration and does not treat the interface as a separately verified deployment.
