Common concerns about Mule 4 upgrade


Do I need to upgrade to Mule 4?

  • The Extended Support for Mule 3.x is expensive and coming to an end in a few months;
  • Using unsupported software is highly risky;
  • Stop wasting investments on outdated technology;
  • Benefit from Mule 4 - build faster and manage APIs easier.

Will the upgrade delay my progress?

  • A marginal delay is unavoidable but the upgrade is  an opportunity to review APIs and requirements;
  • Save time by offloading the migration to a partner while your team focuses on ongoing development;
  • Reduce the number of APIs through redesign and consolidation;
  • Assess the number of licensed cores that you actually need.

How to upgrade without disruption?

  • Involve experts to leverage advanced capabilities;
  • Plan carefully, allocate time and resources;
  • Migration of a large number of APIs might take months and at a significant cost so plan the upgrade well in advance.
  • Take an iterative approach running both Mule versions in parallel where possible.
benefits of Mule4 upgrade

What are the benefits of Mule 4?

  • Never upgrade 'as-is' or move the same point2point mess to a new platform.
  • Enhance the quality of your delivery by leveraging new components, connectors and features.
  • Fully benefit from reuse to accelerate future project delivery and move away from a culture of point2point.
