Migrating WebSphere Application Server to Payara

Migrating applications from WebSphere Application Server to Payara Server 5 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 WebSphere and Payara Server Enterprise 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.

This guide gives you an overview of the differences between WebSphere Application Server and Payara Server, which components and features in Payara Server are equivalent to those in WebSphere, and how to configure some frequently-used resources and features in Payara Server compared to how you’re used to them in WebSphere.
