At R2i, we regularly meet IT leaders who believe their legacy systems are the problem—only to discover that the functionality is solid and the real issues lie in how the systems look or connect.

Before you commit to overhauling your infrastructure, consider these two alternatives that can give your legacy systems a second life: UI improvements and strategic integrations.

1. Modernize the interface, not the whole application

When Mandy joined her organization as IT director, complaints about the systems were immediate and overwhelming. The applications were almost 20 years old, and everyone from customer service to the C-suite hated using them.

Mandy came to R2i for our support to rebuild everything from scratch.

But when we reviewed the systems, we found that the backend was running beautifully. The issues stemmed entirely from the outdated user interface, which was clunky, character-based, and unintuitive.

So instead of a complete overhaul, Mandy worked with R2i to modernize the user interface. Her team kept the stable, functional backend, while replacing the frontend with a clean, browser-based experience. The result? An application that felt brand new—without the cost or disruption of starting over.

As Mandy learned, a refreshed UI can extend the life of your system by years.

For RPG systems, for example, a green screen application can be transformed to look and feel like a modern Windows app—keeping users happy and processes intact.

Ask yourself: Are users frustrated with the application or the interface?

2. Add what’s missing through smart integrations

Sometimes, the problem isn’t what your system does—it’s what it doesn’t do.

If your existing platforms are solid but missing key features, don’t assume you need to replace them. Many gaps can be filled by connecting your system with other tools, environments, or services.

IBM i is especially flexible in this regard. It can integrate seamlessly with:

• Linux and Windows environments
• Unix-based systems
• Web services and modern APIs

Through integrations, you can:

• Add new functionality without replacing the core
• Improve workflows between systems
• Eliminate redundant data entry or manual work
• Extend the usefulness of your current tech stack

When to modernize (and when not to)

If integrations and UI upgrades still leave you short, a full transformation may be necessary. But that decision should never be made lightly.

A total rebuild is expensive, complex, and affects every part of your organization. If you’re going down that road, make sure you’ve:

• Audited your current functionality
• Considered the costs of training vs. replacing
• Partnered with experts who’ve done it before

At R2i, we help clients evaluate their options honestly. And we’re often the first to say: you don’t need to start from scratch.

Extend, don’t abandon

Modernizing your systems doesn’t always mean throwing everything out. With a thoughtful approach, many organizations can preserve what works and improve what doesn’t—without the expense and disruption of a total rebuild.
