 [[preface]]
 == Preface

 This guide explains how to upgrade to {productName} from previous
 of {productName} and Sun GlassFish Enterprise Server product releases.
 Also included in this guide are instructions for upgrading configuration
 data and Jakarta EE applications from binary-compatible earlier versions
 of this software to work with {productName}.
 Finally, this guide describes compatibility issues that affect data
 and applications that are to be migrated.

 [NOTE]
 ====
 The main thrust of the {productName} 7 release
 is to provide an application server for developers to explore and begin
 exploiting the new and updated technologies in the Jakarta EE 10 platform.
 Thus, the upgrade feature of {productName} was not a focus of this
 release. The feature is included in the release, but it may not function
 properly with some of the new features added in support of the Jakarta EE 10 platform.
 ====

 This preface contains information about and conventions for the entire
 {productName} ({productName}) documentation set.

 {productName} 7 is developed through the GlassFish project
 open-source community at https://github.com/eclipse-ee4j/glassfish.
 The GlassFish project provides a structured process for developing the
 {productName} platform that makes the new features of the Jakarta EE
 platform available faster, while maintaining the most important feature
 of Jakarta EE: compatibility. It enables Java developers to access the
 {productName} source code and to contribute to the development of the
 {productName}.
