WildFly to Payara Server Migration
Migrating from WildFly to Payara Server 5 can be a simple and straightforward process because both servers rely on the Java EE specifications. We make it even easier with the help of our migration resources and migration guides:
Planning a Migration to Payara Server
Before your team can start the migration process, you (and the decision makers at your organization) may need to learn more about the Payara Platform. In our ‘Why Migrate to the Payara Platform’ Guide, we’ll provide information about:
- Cloud Native, Containerized, Jakarta EE, and MicroProfile application architectures
- Why makes Payara Server Enterprise the best option for production Jakarta EE (Java EE) applications
- Why Payara Micro is ideal for running Java EE applications in a modern virtualized infrastructure
- The benefits of open source software
- How new Payara Platform Enterprise features are created
- Cost advantages of the Payara Platform

Considerations When Migrating from WildFly to Payara Server
Migrating applications from WildFly to Payara Server can be a simple and straightforward process because both servers rely on the Jakarta EE (Java EE) specifications. However, there are differences in many areas because many Java EE APIs in WildFly and Payara Server are implemented by different components. Moreover, the configuration of certain aspects like external resources, high-availability and deployment is not covered by any specification and is, in fact, very different in both servers.
How to Migrate a Simple WildFly Cluster to Payara Server 5 Deployment Group
This guide will explain the differences between clustering in WildFly and Payara Server, how to plan migration of an existing WildFly cluster to Payara Server, and will also show you how to migrate an example cluster step-by-step.
