In 2025, the American banking sector stands at a decisive turning point in its digital transformation. While customer expectations evolve toward increasingly faster and personalized services, many financial institutions continue to rely on aging legacy systems that limit their innovation capacity. According to Deloitte's study on banking legacy system modernization, maintaining and supporting these outdated systems is becoming increasingly difficult and costly, creating an urgent need for modernization.

The migration to a modern Core Banking Platform now represents a major strategic challenge for ensuring the competitiveness and sustainability of financial institutions. However, this transition must be accomplished without service interruption, a complex technical and organizational challenge that requires a methodical approach and appropriate tools. In this context, low-code platforms like the one offered by Basikon emerge as key solutions to facilitate this transformation.

The limitations of legacy systems in 2025

Technological obsolescence and costly maintenance

The legacy systems that still equip many American financial institutions present major challenges in 2025. These platforms, sometimes decades old, rely on obsolete technologies that require increasingly rare and expensive skills. As highlighted by Deloitte's analysis, the legacy talent shortage is accelerating with the massive retirement of experts in old systems, particularly COBOL programmers, making their recruitment and retention extremely costly.

This technological obsolescence translates into exponential maintenance costs and growing operational risks. Institutions that continue to rely on these systems face frequent downtime, increased security vulnerabilities, and an inability to integrate emerging new technologies. Modernization thus becomes not just a strategic option, but an absolute necessity for business survival.

Rigidity facing regulatory changes

The banking regulatory environment evolves at a sustained pace, requiring financial institutions to have rapid adaptation capabilities that legacy systems can no longer provide. These monolithic platforms, built with rigid architecture, require months or even years to implement new functionalities or comply with new regulations.

This rigidity sharply contrasts with current market requirements that demand accelerated time-to-market and continuous innovation capacity. Institutions equipped with modern systems can deploy new products in weeks, while those using legacy technologies remain constrained by endless development cycles and complex update processes.

Impact on customer experience and competitiveness

Legacy systems now constitute a major obstacle to improving customer experience. Unable to support modern digital functionalities expected by users, they limit institutions' ability to offer innovative services such as instant payments, open banking, or embedded financing solutions.

This technological limitation directly translates into lost competitiveness against neobanks and fintechs that, equipped with modern technologies from their inception, can offer superior user experiences and more agile services. Traditional institutions risk seeing their customer base erode in favor of more innovative and responsive players.

Advantages of modern Core Banking platforms

Cloud-native architecture and scalability

Modern Core Banking platforms rely on cloud-native architecture that offers considerable advantages over legacy systems. Unlike traditional monolithic solutions, these platforms use a modular approach based on microservices that enable horizontal and vertical scalability according to business needs.

This modern architecture, such as that offered by Basikon's Core Banking solution, allows institutions to optimize their resources, thereby reducing operational costs while improving performance. The ability to handle millions of daily transactions without service degradation constitutes a decisive competitive advantage in an environment where availability and speed are critical.

Agility and accelerated time-to-market

One of the main assets of modern platforms lies in their ability to drastically accelerate the time-to-market of new products and services. Thanks to their modular architecture and advanced configuration capabilities, these solutions enable deploying new financial products in days or weeks, compared to several months with traditional systems.

This agility translates into continuous innovation capacity that allows institutions to respond quickly to market changes and evolving customer needs. Low-code platforms, in particular, democratize development by enabling business teams to participate directly in creating and modifying processes without depending exclusively on technical teams.

API integration and partner ecosystem

Modern Core Banking platforms are designed with an "API-first" approach that facilitates integration with the extended ecosystem of partners and third-party services. This native API integration capability allows institutions to quickly create strategic partnerships and enrich their service offerings without complex developments.

According to the Federal Reserve Bank of Kansas City analysis, this modular approach enables institutions to adopt a "best-of-breed" strategy, selecting the best solutions for each specific function while maintaining overall consistency. This flexibility constitutes a major advantage for building a rich and evolving partner ecosystem.

Seamless migration strategies

Progressive approach vs big-bang migration

Seamless migration to a modern Core Banking platform requires choosing between two main approaches: progressive migration or "big-bang" migration. According to the Federal Reserve Bank of Kansas City study, progressive migration, also called component-based migration, presents considerably reduced risks as it allows replacing each core system element one at a time.

This methodical approach enables testing and validating each component before moving to the next, thus minimizing service interruption risks. The example of Zions Bank, which chose to modernize its lending system first before migrating the deposits component, perfectly illustrates this prudent strategy. This regional bank was able to test extensively with thousands of simulations before proceeding with complete migration, guaranteeing total operational continuity.

Data management and operational continuity

Data management constitutes one of the most critical challenges during Core Banking migration. Institutions must guarantee the integrity, security, and availability of millions of customer records while maintaining operational services. Modern platforms like Basikon offer automated migration tools that facilitate this complex process.

The migration approach by "wrapping" or augmenting the existing system represents a particularly effective alternative for ensuring operational continuity. This method consists of deploying a modern platform parallel to the legacy system, enabling progressive transition without risking the stability of critical operations. The Arrawaj client case demonstrates the effectiveness of this approach with successful migration of more than one million customers and four million banking operations in just 18 months.

Team training and change management

The success of Core Banking migration depends as much on human aspects as technical ones. Change management must accompany teams in adopting new tools and processes while preserving business expertise accumulated over years. Low-code platforms facilitate this transition by offering intuitive interfaces that considerably reduce training needs.

Team training must be planned upstream and adapted to different user profiles. The advantage of modern solutions lies in their ability to democratize access to advanced functionalities, enabling business teams to actively participate in configuring and evolving processes without depending exclusively on IT resources.
