[Koha] Backup of Patron Images

Hi, When I migrated my koha from one server to another by migrating the MySQL database, I was able to see the complete data (Bibliography, Circulation, patron, etc) in the new server. However, I could not see the patron images on their profile page, which were earlier uploaded on the old server. I suppose when I migrated the SQL database, it just migrated the data to a new server, but the jpg files were stored in a folder in the koha installation, which is why the photos are not appearing in the new koha installation. Can anyone please help me with migrating the patron images as well? What is the folder location where koha stores the patron images uploaded for each patron? Thank you Rupinder Singh
