Transferring Legacy Before It Costs You More

Why Embedded OEMs Should Offload Aging Products Now—Before Economic Pressure Forces Their Hand

By Ethan Plotkin, CEO of GDCA

Whether markets are tightening or accelerating, portfolios come under scrutiny. In a downturn, cost pressures drive the need to eliminate inefficiencies. In a growth cycle, opportunity costs become the limiting factor—every resource tied up in sustaining non-core products is one less invested in scaling innovation.

In both cases, the question each product must answer is: “Do I still belong here?”

For Embedded OEMs, legacy products are increasingly misaligned with long-term strategic goals. During lean periods, sustaining these aging systems can bleed margins and consume already-stretched teams. In boom cycles, they inhibit agility and slow down the launch of new revenue-generating products. In both environments, the cost of keeping non-core legacy products alive often outweighs the perceived benefit.

This quiet drain is more than financial. It erodes competitiveness. It undermines engineering morale. It burns valuable time that could be spent advancing next-generation solutions or capturing new market share.

The Real Cost of Holding On

Misfit products may not be loud, but they are persistent—and expensive. The drags they create can go unnoticed until the symptoms show up in missed deadlines, shrinking margins, or stressed-out engineering teams. Here’s where the real cost lives:

Engineering Distraction
In most embedded OEMs, engineering talent is one of the company’s most limited and valuable resources. These professionals should be focused on developing new capabilities, supporting strategic customers, and building competitive advantages. Instead, they’re often pulled into sustaining outdated legacy designs.

Take the aerospace sector. A company manufacturing avionics for commercial jets might still be fielding support tickets for hardware certified 15+ years ago—hardware designed on long-retired toolchains by engineers who have since left the company. Engineering teams are forced to chase down part substitutes, interpret incomplete schematics, or rewrite firmware just to keep one airline’s plane operational.

This type of sustainment is complex and time-consuming. It also demoralizes your top talent who didn’t sign up to troubleshoot aging systems—they want to work on the next-gen platforms. In these situations, engineering leadership often has their team spending a lot of time in the past, while the future relentlessly demands their undivided attention.

Margin Decay
Legacy systems are often kept alive through band-aid solutions—manual fixes, undocumented tweaks, and tribal knowledge known only to a handful of long-time employees. These ad-hoc solutions do not scale, and they introduce inefficiencies that quietly eat away at your teams’ bandwidth and profit margins.

Consider a semiconductor equipment manufacturer that still supports an older wafer inspection system used by legacy fabs running mature process nodes. Sales of this aging system have dropped significantly—only a handful of units ship annually—but each requires rare spare parts. At the same time, the company is scaling production of a next-generation inspection platform designed for advanced packaging applications, which is seeing strong adoption across top-tier foundries. Because both systems rely on shared engineering and service resources, sustaining the legacy product adds complexity and delays that slow down the ramp-up of the newer, high-growth product – driving up opportunity cost and putting strategic accounts at risk.

These hidden support costs turn legacy products into sales traps in response to customer orders that draw disproportionately on overhead: labor hours, stopgap workarounds, expensive sourcing, management oversight. And unlike new development, return on this effort is low.

Brand Erosion
For customers in high-stakes industries, legacy systems aren’t optional, they’re critical. In defense, for example, a radar subsystem running on a 20-year-old embedded board may be the only configuration qualified for flight. If that board fails and your team can’t deliver a replacement, or a feasible upgrade, the result isn’t just inconvenience. It’s mission failure.

Delayed responses, broken SLAs, and inconsistent support all erode trust, especially with government and enterprise buyers. One failed shipment can cast doubt on your reliability, not just for legacy products, but for the brand as a whole. And when customers are evaluating new contracts, that damage can carry over.

A single customer escalation tied to a legacy issue can ripple through account teams, procurement groups, and executive relationships. The erosion may be quiet—but it’s far-reaching.

Portfolio Drift
Strategic focus is everything in a competitive market. Yet legacy products often force organizations to break their own rules to keep them afloat: bending lifecycle policies, exceeding target inventory investments, allocating resources off-roadmap, and making exceptions that distract from core initiatives.

This phenomenon is particularly evident in industrial automation. A controls OEM with a strong roadmap in edge computing may still divert team resources to build legacy components because one key customer hasn’t upgraded their factory lines. While the intent is to preserve the relationship, the result is fragmentation: planning becomes reactive, innovation slows, and strategic focus gets blurred.

Over time, these decisions create a portfolio where the mix of legacy products is out of balance with strategic products. You may find yourself saying yes to the past—at the expense of the future.

The Strategic Move: Transfer Before the Pressure Peaks

The true cost of legacy sustainment isn’t always visible—until it’s too late. Many OEMs wait until a crisis forces action: inability to get critical components, or a key engineer’s retirement. But by that point, the options are few, and the cost of recovery is steep.

The better move is to act early, when you have time, talent, and options on your side.

1. Avoid Reactive Redesigns
When an important customer needs a legacy product that requires low-ROI sustaining engineering efforts, OEMs often have a hard time saying no. Instead, OEMs face unplanned “emergency” projects: accelerated re-engineering, urgent part sourcing, regulatory recertification, and customer appeasement. Transferring to a Legacy Equipment Manufacturer (LEM) before that point ensures continuity without a costly scramble.

Example: A defense contractor facing a radar board obsolescence issue proposed a $6M redesign program over 3 years, just to requalify an identical functioning unit. Unfortunately, this was beyond the budget of the end-customer, resulting in equipment cannibalization and degraded readiness. A better outcome could’ve been achieved if an LEM had been engaged a year earlier.

2. Preserve Technical Data and Know-How
Legacy systems often rely on aging documentation, deprecated CAD files, and design knowledge stored in long-tenured employees’ heads. Over time, this institutional memory fades or disappears entirely. By transferring responsibility while that knowledge still exists, OEMs give the LEM access to the assets necessary to ensure a seamless sustainment handoff.

3. Maintain Brand Continuity
With the right LEM, OEMs can ensure customers are not negatively impacted by their decision to cease in-house support of legacy products. That’s because LEMs don’t reinvent the product. Rather, they replicate the supply chain and deliver identical units that meet all original form, fit, and functional requirements. Brand-enforcing quality, regulatory compliance, and customer confidence remain fully intact.

4. Free Up Engineering for New Value Creation
Perhaps the biggest benefit: unlocking your internal teams. Transferring legacy products to LEMs lets your best people stop worrying about decade-old tech and start focusing on innovation, product evolution, and customer value. This is where your true ROI lives, in forward momentum – not in managing the past.

5. Protect Revenue While Shrinking Cost
Because LEMs are optimized for low-volume, high-complexity sustainment, they can take over products that no longer make sense for your teams to support. The result: customers stay happy, recurring revenue stays protected, and internal costs go down.

Visual Summary: “The Hidden Costs of Holding vs. The Strategic Gains of Transferring”

Legacy systems don’t have to be a long-term liability. The sooner you act, the more options and value you preserve.

If you’re ready to reduce risk, refocus your engineering teams, and protect your most strategic customer relationships, now is the time to explore a legacy transfer strategy.
