Is there any criteria to know which app needs modernization?

There are various parameters you can notice in a legacy app that might indicate that you need to modernise your app. Some of the app parameters are:

• Performance issues: if your app is not performing optimally, it means that you need to transform it into a modern app.
• Technology stack: If your app is developed through old-age and outdated technologies or frameworks that don’t support it now.
• Security Issues: if your legacy app is vulnerable to security threats, it is time to hire an application modernization company.
• Compliance issues: If your legacy application does not comply with the latest data and security regulations, go for app modernization.
• Compatibility issues: If your application faces compatibility issues with the newer systems and tools, go for app modernization.
