Transfer your data safely into the new system

An essential component of the replacement of a legacy application is the specialist data migration. Business data migration ensures a smooth transition from the legacy application to the target system. It transfers the data from the legacy application to another specialist application system – the target system – in accordance with a set of rules.

The following aspects are decisive for the success of the specialist data migration:

  • Sufficient understanding of the legacy application through data profiling, system archaeology and industry know-how
  • Systematic GAP analysis including consideration of neighbouring systems
  • Early definition of the migration scope – also for historical data
  • Ongoing review and improvement of data quality
  • Development of test methods
  • Procedure according to script
  • Servicing the actuarial requirements (auditor)
  • Clarification of data protection requirements
  • Dealing with residuals
  • Adequate implementation concept and change management
