Abstract

A focused compilation of links to documents and resources to help you plan and perform your migration from IBM WebSphere Application Server Version 6.1.

FLASH

IBM extended the end-of-service date of IBM WebSphere Application Server (WAS) V6.1 from September 30, 2012 to September 30, 2013. Here is the announcement. This one-year extension of the end-of-service date provides more time to better plan a successful migration. Moving to current versions of WAS provides a much broader set of functions (for both developers and operations) and improves performance and total cost of ownership.

See the first section below for information on special version-to-version migration incentives and assistance.

Migration incentives and assistance
IBM now offers several benefits to make migration to current versions of WAS even easier and more cost effective:
    • A no-charge waiver that expands WAS license entitlements for version to version migration is now available. Contact your IBM representative for details.
    • Assessments are available to assist your migration activities. See the following information from IBM Software Services for WebSphere (ISSW) for details and contact an ISSW rep for a limited quantity of special discount assessment offers.
    • IBM Software Accelerated Value Program provides expertise in custom version to version migrations. The program is currently working with customers to assist in migration planning, avoiding pitfalls, and expediting movement off WAS V6.1. Here are details of the program.
    • The WAS 8.5 Customer Acceleration Program (CAP) provides additional assistance to customers and business partners who have made a commitment to WAS V8.5.x, have an aggressive implementation plan, and agree to provide product references through 2013. Contact Carrie Finneran (carrie@us.ibm.com) for information.
    • IBM Support is pleased to offer our clients Migration Assist (MA). MA is provided by the WAS Level 2 Support team to clients planning a WAS 6.1 to 8.x migration. The Level 2 MA Lead will provide migration guidance, best practices, lessons learned, and answer your migration questions. Download the Migration Assist briefing for details and contact information.

WebSphere Application Server V6.0 Migration Guide
This IBM Redbooks publication will assist in the migration of your WebSphere Application Server installation. The end-to-end migration path includes the migration of the development environment, the test/integration environment, and the production environment using software engineering methodologies. This guide presents best practices in migration strategy and planning, migration tools, and practical migration examples.

A quick guide for migrating to WebSphere Application Server V6.1
IBM WebSphere Application Server includes simple and straightforward tools that remove the complexity of migrating from a previous release to Version 6.1. This overview of the migration process will prepare you for what you need to do and what you can expect so that your migration can be as quick and easy as possible.

SSL, certificate, and key management enhancements for even stronger security in WebSphere Application Server V6.1
Exciting changes have been made to the SSL, certificate, and key management infrastructure in IBM WebSphere Application Server V6.1. This article touches on how these changes will improve security, provide management flexibility and simplification, and maintain a consistent SSL runtime that is tightly integrated with the new configuration.

Planning an iterative migration of a high availability environment to WebSphere Application Server V6.1
Planning is the key to maintaining uptime when migrating a high availability environment to a new version of IBM WebSphere Application Server. This article discusses key points to help you plan to successfully migrate your highly available environment, including how and when to do backups, and how to use those backups should you need to restore your environment.

JDK 5 Compatibility
This document contains information about binary and source incompatibilities between versions 5.0 and 1.4.

CCF-to-J2C Architecture Migration
This IBM Redbooks publication will help you design a solution to migrate an application from the Common Connector Framework (CCF) to the J2EE Connector Architecture (J2CA). As CCF is phased out and the new technology replaces it, customers will find that migration must be planned and executed carefully.

CCF to J2C migration: Part 1: CCF application limitations on WebSphere Application Server V5.0
This five-part series shows you how to migrate applications from the VisualAge for Java™ Common Connector Framework (CCF) to WebSphere Studio J2EE Connector Architecture (J2C). Part 1 describes the CCF application limitations on WebSphere Application Server V5.0. (Terminology note: JCA, the old acronym for J2EE Connector Architecture, is now used to mean Java Cryptography Architecture. The new acronym for J2EE Connector Architecture is J2C.)

Troubleshooting and Support

Solutions to migration problems for Version 6.1
Browse through common Version 6.1 migration problems and solutions that have already been documented and published to the Web.

Collecting data (MustGather)
When a solution cannot be found to your migration problem, you can begin collecting data (MustGather) before calling IBM support. This will help you familiarize yourself with the troubleshooting process and save you time.

Exchanging information with IBM Technical Support
To diagnose or identify a problem, it is sometimes necessary to provide Technical Support with data and information from your system. In addition, Technical Support might also need to provide you with tools or utilities to be used in problem determination.

Instructions for handling certain Out of Memory conditions which occur during migration of an earlier version of WebSphere Application Server to V5.1.1, V6.0.2, or V6.1
When running WASPreUpgrade or WASPostUpgrade, during the migration process from an earlier release of WebSphere Application Server to V5.1.1, V6.0.2, or V6.1, the heap might run out of memory for a complex environment. Either the execution of wsadmin to install the applications, or the migration of the configuration itself, throws java.lang.OutOfMemory errors.

ADMC0009E: The system failed to make the SOAP RPC call
During the first step in a federated migration the WASPostUpgrade process connects to the migrated Deployment Manager process and synchronizes the configuration with the backup directory. When the configuration is very large, a timeout may be encountered. To alleviate this issue, follow the instructions in the Information Center for increasing the SOAP timeout value.
