I installed 1.11.0 war and module files from Reference Application 2.3.1. After following complete installation process I was able to see new UI which we see on demo link. However as I was not having enough data I took demo-1.12.0.sql from demo data link of openMRS. But once I executed that file and restarted tomcat some of openmrs modules started giving exception and stopped working. Does anyone know how to resolve this? Or which data file I can use with Reference Application 2.3.1 ? I need data file for almost 500 patients. Someone please help.
