Moreover, a rollback of the upgrade should be possible at any time. The method disclosed here comprises the steps of creating a new table in said database, copying and/or transforming data from said table to said new table, adding a new version of said stored procedure to said database, and adding an additional stored procedure to the database which refers to both the previous version and the new version of the stored procedure whenever data is to be processed with the stored procedure, for causing data processing to take place in accordance with the previous version and the new version of the stored procedure.
