Miroslav Katsarov is the CEO of Modeshift, a technology company bringing intelligent transportation to small- and mid-size transit agencies.getty​It’s a complex, high-stakes endeavor to modernize legacy systems, characterized by high costs, operational risks and the need to align diverse stakeholders. The transit industry illustrates these challenges clearly, where the push for digital transformation often means navigating deeply fragmented systems with multiple partners, payment types and outdated infrastructure. ​Modernization efforts for legacy industries like transit should no longer be just a "rip-and-replace" project, but rather a strategic, incremental evolution. As a result, tech leaders must shift their focus toward creating account-based structures that can coordinate multi-stakeholder environments, payment methods and distribution channels in a gradual, flexible and scalable way. ​Modernization Should Be Incremental, Not Disruptive ​Digital transformation is about far more than just replacing old with new technology. The reality is that legacy systems won’t disappear any time soon; they will simply be absorbed into new architecture, becoming part of a larger, more interconnected ecosystem. Prioritizing gradual integration over total system replacement allows businesses to evolve without forcing behavior change. This minimizes the risk of being locked in lengthy procurement processes, which are often the reason for inflated costs and numerous inefficiencies. Major system overhauls lead to service disruptions, including security vulnerabilities, downtime and migration issues.Platform Architecture Determines Long-Term FlexibilityThe advent of cloud-native platforms has enabled industries to integrate legacy systems, automate partner distribution and optimize transaction costs without disrupting entire systems.Technology leaders should prioritize API-driven, modular platforms to avoid full system overhauls. This approach enables organizations to connect, swap or scale components as needed. The winning model here is a coordinated platform ecosystem, not fragmented vendors or rigid monoliths. This model supports shared visibility and a trusted data layer across stakeholders. In multi-partner environments, it enables better tracking of usage, revenue and entitlements without relying on inflexible systems.Cloud-Based, Multi-Partner Platforms Enable Flexibility Without Lock-InMulti-partner collaboration through shared SaaS platforms allows organizations to work across partners while maintaining the flexibility to choose the right providers for their needs. Subscription-based models make it easier to switch vendors over time, avoiding lock-in to a single proprietary system.These platforms are typically built on account-based, API-driven architecture, which allows legacy systems to be integrated (not replaced) while supporting multiple payment types, partners and distribution channels. This also enables more efficient fare distribution at scale, including automated eligibility and validation for programs like institutional passes.By leveraging open APIs and cloud-agnostic tools, organizations can streamline migration and integration while reducing the constraints of fragmented systems and siloed data. The result is better coordination across stakeholders, improved visibility into usage and revenue and a more consistent experience across modes and providers.Coordination Requires VisibilityJust as importantly, these systems provide a unified view across partners, systems and channels that is often missing in legacy environments. By bringing interactions into a more unified interface across touchpoints, organizations can move away from fragmented systems and siloed data that limit coordination.This creates a more complete, 360-degree view of operations, allowing stakeholders to better understand how access, pricing and services are being delivered across an entire network. The result is improved visibility and a stronger foundation for coordination across distributed partners.How Share-A-Pass Models Illustrate Scalable, Partner-Driven DistributionInstitutional transit pass programs and share-a-pass models illustrate how organizations can distribute access at scale through strategic partnerships, in this case with employers, universities or residential communities. At their core, these models reflect a broader shift toward platform-based distribution, where access, pricing and eligibility can be managed dynamically across multiple stakeholders.For transit, this usually encompasses broader shifts toward fare payments-as-a-service (FPaaS), where modern mobility platforms play an instrumental role in coordinating distribution among operators and partners. More broadly, this approach shows how organizations can distribute access and pricing across a network of partners, rather than managing them within a single system or channel.The Benefits Of Regional Coordination Without Centralization​Multi-partner ecosystems can scale successfully when there’s a shared, underlying system that connects users, access and entitlements without relying on a single channel or transaction.​This model incorporates account-based structures that separate identity, access and payment, enabling effective coordination without forcing a single system or vendor. A notable example of this in the U.S. is the NEORide partnership, which consolidates over 17 different transit operators across Ohio, Kentucky and Michigan, using a shared FPaaS platform. This allows multiple agencies to deliver unified ticketing solutions under one regional system, improving transparency and accessibility for both users and authorities. The future of legacy industries won’t be defined by who replaces systems fastest, but by who coordinates them best. In multi-partner environments, flexibility, visibility and interoperability will determine long-term success.​Forbes Technology Council is an invitation-only community for world-class CIOs, CTOs and technology executives.
