- Outdated Runtime (Mule 3.9): Security risks, limited features.
- End-of-Support for Runtime: System instability, business disruption.
- Maintaining Legacy Integrations: Difficulty with modifications and troubleshooting.
The client faced a critical challenge with 2 core Mulesoft applications, cx-coreapi, and cx-batchapi, these applications were running on the nearing end-of-life Mule 3.9 runtime. This posed significant risks. Continued use could lead to business disruptions like system instability and integration failures. Security vulnerabilities from the outdated runtime increased the risk of data breaches and attacks. Additionally, limited functionality and scalability restricted access to new features and hindered future growth.

The project’s scope was successfully modernizing the Company’s integration platform, ensuring its long-term stability, security, and operational efficiency. This was achieved by Mule 3.9 to Mule 4 Migration for our client. The project scope encompassed the following key elements:
- We assessed, migrated, tested, and documented everything for a smooth and secure upgrade.
- We facilitated Mule 3.9 to Mule 4 Migration for the latest security features and a faster system.
- We optimized the client’s code to match Mulesoft’s latest standards for better performance and maintainability.
- We implemented key security features to keep their data safe and sound.
