Modernization

April 10, 2023 6

Rewriting from scratch

• Very expensive and cost-ineffective

• Long “time-to-production” cycle

• Wasting of resources for maintaining of the existing application during the development of the new one.

• Risky in terms of budget, time and functionality

??

Automated Modernization

• The existing application logic is automatically preserved• Low risks in terms of the project scope and schedule• Easier deployment and shorter end-user learning curve• You always can go back• Maximum use of the existing manpower
