Integration has become an essential ingredient in the success of any organization, as it increases the sprawl of applications, infrastructure and the partner ecosystem. Businesses with the proper integration strategies have raised the bar with lower operational costs, faster project delivery and smart revenue streams. They are quickly leaving more traditional players far behind. An integration strategy allows organizations to connect in the right way, overcome obstructions and drive tangible business value. By quickly connecting new information and operationalizing it across the entire enterprise, organizations can increase productivity, ensure tighter security, and help the organization stay competitive in their industry

Migration Considerations

MuleSoft AnyPoint Platform provides a powerful technology platform that provides enterprises with robust API implementation solutions and strategies. Between its last major release, 3.0, in 2010 and its current state, MuleSoft has advanced a lot, from being just an Integration/ API platform to assist in legacy modernization, implementing secure SaaS integrations, and providing full API lifecycle management. MuleSoft AnyPoint Platform allows organizations to implement, integrate, connect and build its enterprise solutions in new ways. The next-gen Mule 4 platform offers a broad range of new and improved features intended to enhance the platform's capabilities along with developer experience. In this blog, we try to address the benefits, challenges and best practices for organizations looking to migrate from 3 to Mule 4.
  • Extended Support - No new applications can be created on this version. Existing applications on the version continue to run and can be updated or restarted. It will be possible until the End of Life (EOL) or End of Extended Support for that version.
  • End Of Life Support - The current version is removed from CloudHub. Existing applications will continue to run, but they will fail to restart once they are stopped. Updates will be blocked.
  • Beyond End-of-Life Support - Applications on this version will be stopped and removed from the platform.

Why Migrate?

Running applications and data on unsupported versions can slow down the pace of innovation and delivery for your business. Whilst the ramifications of ignoring the end of support may seem less daunting than migrating. It is a great opportunity to transform your applications and infrastructure, take advantage of the features and improvements introduced in the latest versions of Mule, and benefit from:
  • Reduced complexity

  • Improved efficiency

  • Optimized cost

  • Continued support

  • Faster delivery

  • Minimized business impact

  • Accelerated speed-to-value
