Downgrade Netezza Performance Server systems that have stored procedures

If you downgrade your Netezza Performance Server release, the stored procedures should continue to work after the downgrade. If the downgrade release does not support all the NZPLSQL features of the later release, any procedures that use those features will fail when executed after the downgrade. You can drop or alter those procedures to ensure that they conform to the NZPLSQL language support of the Netezza Performance Server release that your system is running.
