30 Jan 2008 This tutorial describes how to emulate your entire legacy configuration and extend new functions, such as HTTP traffic shaping, centralized management facilities, and application versioning by using only a single license of WebSphere® Extended Deployment (XD) version 6.1. This technique lets you avoid an upgrade of your entire older cell in order to use new product features. In this tutorial
You learn how to:
- Support and extend newer function to you older legacy cells, without requiring product upgrades.
- Use wsadmin scripts to automate tasks, such as mirroring a legacy cell within a newer version.
Prerequisites
- Jython
- Using WebSphere to manage J2EE applications
- Familiarity with the WebSphere user interface
System requirements
- WebSphere Extended Deployment Version 5.1 deployment or cell.
- WebSphere Extended Deployment Version 6.1 cell, specifically a deployment manager.
- Security privileges to connect to both deployment managers if security is enabled.

Summary
Migrating from one version of an application server to another causes issues for even the most well-structured information systems. This is apparent when migrating to complex and advanced application servers, such as WebSphere, and crossing large development gaps, such as those exposed in an upgrade from one major release to the next. In this case, you required to upgrade an entire topology to fully take advantage of the new features. However, such transitions are usually considered in the middle of running applications in production. WebSphere Extended Deployment (XD) version 6.1 addresses these issues by emulating your entire legacy configuration and extending new functions, such as HTTP traffic shaping, centralized management facilities, and application versioning, using only a single license of XD version 6.1. You can automate the entire process of migrating or importing your legacy configuration into a newer cell by using the automation facilities provided by XD version 6.1. This tutorial serves as both a guide and an introduction on how to extend some of XD version 6.1's functions to a version 5.1 cell.
