It’s not like there’s a textbook out there prescribing specific procedures for embracing legacy modernization at your firm. And you’re probably aware of the reason: each situation is unique. Still, we can single out several major approaches. Among them, you can find the right application modernization strategy to address your situation.
Replace with a New System
A radical overhaul of the company’s IT infrastructure bahrain phone number data and underlying software is the most common approach to the modernization of legacy applications. And it’s pretty evident too: rebuild the whole thing from the ground up.
Benefits:
- Offers unlimited modernization potential
- Invites to rethink and optimize business processes
- Ensures substantial gains on ROI and other key metrics over the short and long-term
Risks:
- Takes longer to implement
- Requires significant investment
- Suggests running of two systems until the final switch
The replacement strategy was the one we applied for the century-old family business operating greenhouses. Yet, we left the time-tested ultimate guide to corporate tax in japan algorithms intact, taking them and putting into a modern, secure cloud application.

Rebuild Gradually
Another proven way to modernize your software is the app-by-app approach. In this scenario, you pick the most ROI-effective applications in the legacy solution and rebuild them one by one.
Benefits:
- Moderate modernization potential as remaining legacy parts will be holding back
- Requires less management and investment resources (compared to total system revamp)
- Makes the min negative impact on running business operations
Risks:
- May involve too many integrations with the existing legacy system to ensure business continuity
- Does not work well when several components are being rebuilt simultaneously

Reuse
And the least invasive legacy system modernization approach is, of course, to reuse the existing IT infrastructure as much as possible. Here is how you can get there:
-
Encapsulate
The legacy software remains the same, and some of its parts become available for integration with other systems or applications via an API layer.
-
Rehost / Replatform
The legacy system gets migrated to a new physical or virtual server. That’s when old software ends up in the cloud and becomes more accessible, but carries over its other limitations. This scenario may involve slight changes to make sure your solution runs error-free on a new platform.
-
Refactor / Rearchitect
With this scenario, a legacy system’s codebase gets substantial updates and modifications to speed up its performance and remove technical debt. But its core functionality remains the same.
