Executive Summary
mindit.io partnered with one of Romania’s top five banking institutions to support the migration of their outdated integration architecture to TIBCO ActiveMatrix Business Works 6. The client’s legacy setup, built on two separate integration platforms – one of which was significantly outdated – resulted in increased complexity, technical debt, and operational risk. With a focus on agility, security, and future-readiness, the migration enabled a modular, API-first, microservices-ready architecture while ensuring minimal disruption to business operations.
Key Results
- Successfully migrated over 200 ESB interfaces to an API-first architecture
- Integrated TIBCO Business Works 6 as the primary platform with minimal business impact
- Improved agility and cross-team collaboration through a customized SCRUM approach
- Enhanced system security and reusability through standardized REST APIs and secured communication
- Decommissioned legacy components while supporting business continuity
About the Client
The client is one of the top five banking institutions in Romania, part of a major European banking group. Their operations involve highly complex business logic, numerous technical integration points, and a need for robust, scalable, and secure enterprise architecture. In pursuit of greater standardization, agility, and modernization, the bank initiated a full migration from legacy ESB solutions to TIBCO Business Works 6.
The Challenge
The bank faced key technical and strategic challenges:
- Achieve cross-team agility while aligning with the Agile Manifesto
- Decide between direct migration or redesign to maximize standardization
- Ensure business continuity while decommissioning old platforms
- Adhere to strict security standards to prevent data leakage
Project Goals
mindit.io was brought in to:
- Migrate integration flows from the outdated platforms to a modern ESB framework
- Replace legacy SOAP services with lightweight REST APIs
- Introduce microservices-ready architecture and containerization
- Preserve business continuity with minimal downtime
- Enhance security through standardized authentication and encrypted communications
mindit.io’s Solution
Working alongside the client, mindit.io implemented a tailored, agile migration strategy. Two agile teams worked in unison, leveraging their knowledge of the existing integration platform and business architecture. Using CI/CD pipelines, delta deployments, and comprehensive testing practices, the teams ensured seamless transitions while maintaining live services. We replaced SOAP services with RESTful APIs and used TIBCO BW6’s out-of-the-box connectors for standard integration needs. In complex cases, custom plugins and components were developed for specific data transformation scenarios. Communication was secured using HTTPS, role-based user authentication, and platform-level access management.
Technologies: TIBCO ActiveMatrix Business Works 6, IBM WebSphere ESB, IBM MQ, Java, Spring Boot, GIT, Jenkins, Maven, Docker, OpenShift, Jira Software, Confluence
Results
The migration resulted in a streamlined, unified integration platform that significantly improved maintainability, scalability, and development speed. Over 200 ESB flows were transitioned to reusable APIs, reducing complexity and enabling microservices adoption. The new platform improved adaptability to changing business needs and ensured system reliability with secure service orchestration and minimal operational disruption.
