Legacy Systems Still Matter

In partnership with

In a world obsessed with shiny new tools, let's pour one out for the unsung heroes of your tech infrastructure: legacy systems. You know the ones…that crusty ERP system from 2005 or the database that runs on what looks like ancient hieroglyphics.

While everyone's talking about the latest tech darling, I'm here to remind you that those old workhorses deserve a seat at your strategy table.

Your Business Runs on "Boring"

I once worked with a manufacturing firm whose CEO was desperate to modernize everything. "We need to be cutting-edge!" he proclaimed. Meanwhile, their 15-year-old inventory management system quietly processed thousands of transactions daily without complaint.

When we finally replaced it, guess what happened? Three weeks of operational chaos.

The truth of the matter is that:

• Legacy systems often handle 60-80% of your critical business processes

• They've been battle-tested through years of actual use

• Your staff knows how to use them (and all their quirky workarounds)

The "replace everything" mindset is expensive in ways that won't appear in your initial ROI calculations. A few examples:

1. Knowledge transfer is messy. That developer who configured your legacy CRM? She left five years ago, and the documentation exists only in people's heads.

2. Integration debt piles up. Every new system needs to talk to something old, and each integration is another potential failure point.

3. Business disruption isn't theoretical. The costs are real and immediate when critical systems go down during transition.

Instead of wholesale replacement, consider these approaches:

• Selective modernization: Identify which legacy components limit business growth and focus first.

• Middleware solutions: Use integration layers to connect modern front-ends with stable legacy back-ends.

• Documentation: Make capturing institutional knowledge about legacy systems a priority before it walks out the door…or gets hit by a bus.

Technology strategy is about creating a sustainable competitive advantage, and sometimes, the most strategic move is understanding what not to change.

That ancient COBOL application might not be sexy, but neither is explaining to your board why orders can't be processed for the third day in a row.
