Dear Team,I have installed both the version VIVO 1.12 and 1.13 versions. When I restart the Tomcat, Thumbnail is automatically removed from the profile of the scholar.I have not configured the MySQL / MariaDB 5.5 or later (or any other supported by Jena SDB) because it is optional. So, my question is then where the data is stored. So, Can I move from the 1.12 to 1.13 version?What is the setup involved in upgrading the version from 1.12 to 1.13?
