TransformationTransformation phase can be commenced after integration testing phase. It will entail thefollowing steps:a) Identify the fields, columns to be added/deleted from the existing systemb) Identify the default values to be populated for all ‗not null‘ columnsc) Develop routines to create (Entry if any by data entry operators), migrate,convert the data from hard copies, old database (if any), computer records tothe new databased) Develop test programs to check the migrated data from old database to thenew databasee) Test the migration programs using the snapshot of the production dataAssam Police Page 149
