  • The business has workarounds in these situations, and it establishes a healthy data check-up and the exceptions are flagged allowing the team and the firm to react accordingly.
  • In stage B- the SWP standard format data is loaded into SWP staging database using standard data transformation tools. In stage C, data is loaded into SWP production database.
  • The migration tools and associated validation programs are built to transform the data per agreed specifications. These tools are run in a repeatable sequence to transform, validate and load the data into a sample SWP application instance. Once the data is fully migrated, the members of the firm will have access to these instances so that they can also validate the data as per the expectation and business needs.
