Hi developers,

Hi Roopesh, 
 
Could you please verify whether you have redirected the catalog-dita.xml file of your newly installed DITA-OT environment towards the Catalog file used by SDL Knowledge Center. 
 
Please verify the contents of the catalog-dita_template.xml file as available in the OOTB DITA-OT\Infoshare location with the content of the catalog-dita_template.xml file as available in your new DITA-OT instance. 
Reusing our catalog through the redirection mechanism should solve your issue. 
 
Kind Regards, 
 
Raf
