Frequently
asked questions?

What is the difference between app modernization and replatforming?

App modernization is a broader process that includes updating the app’s code, UI, and architecture, while replatforming usually focuses only on migrating the app to a new environment without major code changes.

How long does app modernization take?

The timeline typically ranges from 4 to 12 weeks depending on the scope, with phased delivery allowing quicker results and minimal disruption to existing operations.

Will I lose data during modernization?

No, data is securely backed up and transferred as part of the process, ensuring full integrity and compliance throughout the modernization journey.

Can we modernize our application in phases?

Yes, phased modernization is highly recommended to reduce risk, allowing you to upgrade critical components first while continuing regular business operations.

Is app modernization expensive?

While there’s an upfront investment, it significantly reduces long-term maintenance costs and improves performance, leading to better ROI and customer satisfaction.
