About This Guide

This Migrating and Redeploying Server Applications Guide describes how J2EE applications are migrated from earlier versions of the Sun ONE Application Server (formerly known as `iPlanet Application Server') to Sun ONE Application Server 7.

In addition, this guide describes how NetDynamics applications and applications from the Netscape Application Server (NAS) are migrated to the Sun ONE Application Server 7.

This manual is intended for system administrators, network administrators, application server administrators and web developers who have an interest in migration issues.

How This Guide is Organized

---

This guide is organized as follows:

• About Sun ONE Application Server 7 - describes the architecture of the Sun ONE Application Server 7 and the differences between J2EE standards and application components implemented with this version of the Sun ONE Application Server versus previous versions.
• Migration and Redeployment - describes those application components that need to be migrated and why, as well as the redeployment process for migrated applications.
• Migration Considerations and Strategies - describes considerations and strategies for migrating applications from competing platforms and from previous versions of the Sun ONE Application Server. There are also sample migration applications included that provide an end-to-end description of the migration process.
• Automating Migration - describes the available automation tools used to migrate applications from competing platforms and earlier versions of the Sun ONE Application Server.
• Redeploying Migrated Applications - describes how migrated applications are redeployed to the Sun ONE Application Server.

Documentation Conventions

---

File and directory paths are given in Windows format (with backslashes separating directory names). For Unix versions, the directory paths are the same, except forward slashes are used instead of backslashes to separate directories.

This guide uses URLs of the form: http://server.domain/path/file.html, where:

• server is the name of the server where you are running the application.
• domain is your internet domain name.
• path is the directory structure on the server.
• file is an individual filename.

The following table shows the typographic conventions used throughout Sun ONE documentation
