Legacy Transformation

In Geval6, we understand that while the vast range of latest technologies are exciting, there are a large number of customers who still heavily depend on mission critical business applications running on technologies such AS/400.


Old is Gold and New is Diamond


While Geval6’s legacy transformation primarily revolves around AS/400, we believe that we have the ability to smoothly replicate these services on other legacy platforms.

Customers who run business applications on legacy platforms including AS/400, have the following challenges

  • Applications running on these platforms for ages are mission critical and robust, hence replacing them is not a solution

  • In this age of competition, there is ever growing demand for more functionalities, some of which are business process enhancements but rest are aligned to newer technologies such as cloud, mobility, AI etc.

  • Customer’s main challenge in achieving these demands is availability (and retention) of legacy skills.

This is where Geval6 is able to support our customers through our technology team, which has expertise in heterogonous technologies including legacy platforms. Those with legacy skillsets are also able to get opportunities to work on other technologies and vice-versa. This ability helps us to retain and grow the skills required to provide legacy transformation services.

Our Process

We have a 4 stage methodology to reach to a settled state. Legacy applications are invariably mission critical ones and taking over requires a process driven approach which is what is described below

  • This would be Knowledge transfer stage where knowledge about the current computing environment will be gathered including about the

  • Business processes

  • Applications

  • Protocols & Processes

  • The required infrastructure and the connectivity would be setup during this stage.



  • Once the knowledge has been gathered, infrastructure has been setup, live tasks will be handled in parallel to customer's efforts. This would help in

  • Fine tuning the processes and the infrastructure.

  • Strengthen our understanding of the Business Processes and applications.

  • Establish the collaboration with the customer.

Steady State
  • At this stage, customer would handover live tasks in a phased manner and our team would have been plugged into customer's operational process. In this stage, Geval 6 would

  • Handle production support.

  • Take care of development support.

  • Adhere to SLA levels established.

Steady State

Auto Pilot

  • A tailored Agile process would be used for efficient delivery.

  • Customer would be almost hands-off and can focus on new initiatives.
