The database schema for Task applications was changed slighlty from the 1.0.x to 1.1.x version of Spring Cloud Task. Since Spring Cloud Data Flow automatically creates the database schema if it is not present upon server startup, you may need to update the schema if you ran a 1.0.x version of the Data Flow server and now are upgrading to the 1.1.x version. You can find the migration scripts here in the Spring Cloud Task Github repository. The documentation for Accessing Services with Diego SSH and this blog entry for connecting a GUI tools to the MySQL Service in PCF should help you to update the schema.
