This will be resolved in a future release of CABI.
Workaround:
Before starting the upgrade installer, execute the below query in the mysql database:
ALTER TABLE jasperserver.JIResourceFolder RENAME jasperserver.JIRESOURCEFOLDER;
Before the install is executed (where the install actually runs) , however, the following query must be run:
ALTER TABLE jasperserver.JIRESOURCEFOLDER RENAME jasperserver.JIResourceFolder;
