Upgrade Your System, Maximize Your ROI: A Practical Look at How Organizations Can Modernize Their Warehouse Software Systems with Minimal Risk and Maximum Return
Takeaways
- Planned software upgrades minimize downtime and keep critical systems running reliably.
- Phased modernization allows operations to continue while aging systems are replaced.
- Working with experienced engineers reduces risk and ensures long-term system stability.
The challenge of modernizing legacy warehouse systems
Automation installed decades ago continues to power warehouses around the world. Some of those systems still run on Fortran or C, while others depend on early warehouse management platforms that have simply aged out. Whether the software is 20 years old or just starting to show its age, the next upgrade must improve performance without slowing production.
Making that happen isn’t always easy. Because most warehouse systems run around the clock, even brief interruptions can disrupt order flow, labor, and customer commitments. A deferred approach to upgrades and modifications may avoid short-term disruptions, but it can create even bigger issues later — when outdated systems finally run out of steam.
Not all upgrades carry the same level of complexity. Technical upgrades — such as updating the operating system, database, or Java version — are relatively routine and help keep applications running on modern, secure infrastructure. Software platform migrations, on the other hand, are more extensive. They involve rebuilding business processes within a new system to support current operations and security requirements.
Changing business processes also limits operational performance. Adding new equipment, connecting to cloud systems, or sharing real-time data across sites become harder every year. The code, hardware, and documentation that once fit perfectly together start to age out. When that happens, even small fixes take longer and carry more risk.
Security has also become a growing concern as companies revisit legacy platforms. “Many older applications never considered today’s security standards,” says Stefan Loegl, Dematic Software Modernization Manager. “As soon we start an upgrade project, questions invariably come up about authentication, interfaces, and data protection.”
Dematic Lifecycle Solutions & Service helps organizations modernize without disruption. By evaluating current systems, addressing compatibility issues, and designing phased upgrades, the Dematic team experts works with companies to reduce risk and extend the life of their operations. Systems perform better, and they are easier to maintain, modify, and expand.
You can’t avoid the inevitable
Companies delay software upgrades for different reasons. Fear of downtime, cost, and complexity top the list. Most operations also run at full capacity with no room for downtime, which actually makes waiting to upgrade cost more in the long run. Outdated software introduces security gaps, deviates from actual business demands, and likely relies on a shrinking group of engineers who know how to maintain it. As time goes on, maintenance costs rise, and vendor support eventually ends.
Dematic Lifecycle Solutions & Services helps companies move forward with upgrades that are planned, tested, and verified before a single line of code changes in production. Using emulation and phased implementation, Dematic modernizes critical systems while operations continue.
Upgrades also preserve existing interfaces between host systems and control levels, allowing operations to continue without reworking established connections. Keeping those interfaces intact helps minimize risk before any testing begins in the virtual environment. “Upgrades are inevitable, but they don’t have to stop production,” says Loegl. “By testing every process and even a full day’s workload in a virtual environment first, we can minimize onsite testing and keep downtime to an absolute minimum.”
A phased approach
Using a phased approach, even the biggest modernization project will result in a stable future. As an example, there is an Austrian hardware supplier serving trade professionals running one of the most complex logistics sites in Europe. Over the years, the facility expanded piece by piece into a massive, automated network of conveyors, pallet cranes, and sorters.
Dematic first implemented automation at the site in the mid-1980s, and the operation continued to perform reliably as the business grew. By 2024, however, the original software had reached the end of its support cycle. Operational complexity had increased, with more than 20 programmable logic controllers (PLCs) managing miles of conveyor and high-bay storage equipment, processing around 250,000 messages per hour.
Updating the software stack was the next logical step to ensure long-term reliability and support for new technologies. Dematic Lifecycle Solutions & Services approached the upgrade through a three-phase migration that kept the operation running at full capacity. Each phase focused on a distinct part of the system to reduce risk and maintain stability:
- Phase 1: Replaced the simplest external equipment and refreshed the interface with the customer’s host system to create a stable foundation for future upgrades.
- Phase 2: Updated the pallet-handling processes, ensuring smooth integration with existing controls and minimizing disruption to ongoing workflows.
- Phase 3: Modernized the tote-conveyor network, optimizing routing and implementing a dynamic routing algorithm that allows totes to reroute automatically when blockages occur.
This phased approach minimized risk, eliminated downtime, and added new functionality along the way. “By upgrading in stages, we kept operations stable, reduced risk, and added new functionality that delivered measurable business value,” says Loegl, “It was not just a software refresh.” All functionality and performance were verified in a virtual environment before onsite testing.
The project proved that even the most complex, decades-old software can be modernized without stopping production. The phased approach kept the operation running while every core system was upgraded. The operation now runs faster, handles more volume, and provides a stable base for future expansion.
Future-readiness starts here
For each year a system falls behind, it becomes harder and more expensive to bring it back up to date. Software upgrades aren’t just about keeping old systems running. They are about providing the necessary flexibility and scalability for long-term performance.
“Modernization is always more affordable than fixing a system after it fails,” says Loegl. “Software and security standards change fast, and companies can’t afford the risk running without updates.”
Dematic Lifecycle Solutions & Services guides organizations through every step — from evaluation to implementation — with proven methods. With the right partner, software upgrades go from a disruption and to an integral part of a smarter, more resilient operation.
