Strategies for a Successful Coexistence of O11 and ODC

In the rapidly evolving software development landscape, the coexistence of legacy systems alongside emerging platforms presents a unique set of challenges and opportunities. As organisations navigate this transition, it becomes crucial to devise strategies that ensure seamless integration and maximise the benefits of both worlds. This article will explore key strategies for the successful coexistence of OutSystems 11 (O11) and OutSystems Development Environment (ODC), offering insights into prioritisation, migration approaches, data interoperability, and architectural considerations.


Understanding Coexistence:

In the context of software systems, coexistence refers to the simultaneous existence and interaction of different platforms or applications without compromising functionality or user experience. In the case of O11 and ODC, coexistence entails leveraging the strengths of each platform while ensuring compatibility and interoperability between them.


Prioritisation and Phased Migration:

One of the fundamental strategies for successful coexistence is prioritisation based on suitability for migration. Not all applications within an organisation’s portfolio may be ready for migration to ODC. Therefore, adopting a phased approach to migration is recommended, where applications that align well with ODC’s features and capabilities are migrated first. This ensures a gradual transition while minimising disruption to ongoing operations.


Data Interoperability and Integration:

The seamless data integration between the two platforms is central to the coexistence of O11 and ODC. Organisations must devise strategies for data interoperability, enabling new applications built on ODC to leverage data from existing O11 systems. This may involve implementing APIs to expose O11 data for consumption by ODC applications and vice versa. By ensuring smooth data interchange, organisations can maintain business continuity while harnessing the power of both platforms.


Architectural Considerations:

Coexistence necessitates careful consideration of architectural principles to ensure compatibility and scalability. Organisations should embrace service-oriented architecture (SOA), which promotes loose coupling and modular design. Transitioning towards SOA facilitates integration between O11 and ODC and modernises the overall application portfolio, making it more adaptable to future technological advancements.


Best Practices and Recommendations:

  • Adopt a phased approach to migration, prioritising applications based on suitability for ODC.
  • Leverage APIs to enable seamless data interchange between O11 and ODC applications.
  • Embrace service-oriented architecture to promote modularity and interoperability.
  • Continuously monitor and evaluate the evolving features and capabilities of ODC for potential migration opportunities.
  • Ensure thorough planning and risk mitigation strategies to minimise disruption during the migration process.



In conclusion, the successful coexistence of O11 and ODC requires a strategic approach that balances continuity with innovation. By prioritising migration, ensuring data interoperability, and embracing modern architectural principles, organisations can unlock the full potential of both platforms while mitigating risks and maintaining operational efficiency. As the technology landscape continues to evolve, embracing coexistence as a strategic imperative will be essential for organisations striving to thrive in an ever-changing digital ecosystem.
