Effective IT-OT integration for end users requires early collaboration between IT, OT, engineering, and OEMs to avoid costly delays and compatibility issues. However, one challenge that stands in the way is figuring out how to handle legacy equipment.
That’s according to PMMI Business Intelligence’s “Performance Optimization: Insights for Packaging Line Readiness,” a report that brings together key issues, industry insights, and recommendations from roundtable discussions and panels featured at the 2025 Top to Top Summit from February 23–25. The summit serves as a platform for OEMs and CPGs to exchange perspectives, address shared challenges, and collaborate on practical solutions.
Most participants were from the food industry (61%). Pharmaceuticals, another notable sector, represented 7% of participation.
End users experience difficulties in eliminating legacy equipment, whether due to cost constraints or the specialized nature of certain machines, the Business Intelligence team finds.
One panelist, an expert in engineering and manufacturing excellence, admitted to having to keep some legacy systems, referring to them as “islands” isolated from newer technologies. Dealing with legacy equipment can mean replacing it or finding solutions that minimize downtime and cost.
Another panelist, an expert in IT from a large CPG, discussed an experience starting a successful digital transformation four to five years back, investing heavily in equipment upgrades to more compatible future-proof solutions. This included outfitting the entire operation, from the plant floor and OT layer to the IT layer, with new technology. The upgrade eliminated 80% of legacy equipment and aligned with modern IT-OT standards.
In the short term, OEMs can support IT-OT integration by offering hybrid solutions that enable older programmable logic controllers (PLCs) and OT networks to exchange data with modern systems. Longer term, end users upgrading to more compatible equipment can future-proof operations and mitigate challenges. Users want OEMs to develop machinery with built-in connectivity, which reduces reliance on traditional computers and ensures seamless integration.
