Hi, I am Steve Robinson, an independent WebSphere Application Server Migration Consultant

IBM WebSphere Application Server (WAS) version 8..x.x.x (WAS 8, WAS 8.5, WAS 8.5.5, WAS 8.5.5.x) versions have been available for a while now, and so organizations are now evaluating migration of existing WAS 7 application server environments along with applications to the newer stable and updated version of IBM WebSphere Application Server. IBM supplies tools to help with the migration of a WAS profile from WAS 7 to WAS 8.x, which are simple if used correctly, however, application design can thwart the process and be an area of concern. I can help with planning, architecture and automation of much of the process.

If you have need of services such as:

  • Migration Automation
  • Migration Approach & Strategy
  • J2EE, JEE Application Migration support
  • General WebSphere thought leadership

Then please feel free to have a chat. My contact details are on my contact page.

Regards,

Steve Robinson – IBM Champion 2013

Migration tools

IBM provides several tools to make migration from an earlier version as smooth as possible. WAS v8.x migration tools support the migration from WAS v6.0, v6.1 and v7.0. The following diagram explains the application of these tools.

There are many things to be migrated, but the most important things are

  • Migration of application server configuration (profile)
  • Migration of applications

IBM provides several tools to help with the migration process, for example, the IBM WebSphere Application Server Migration Toolkit is a suite of tools and knowledge collections that enables your organization to quickly and cost-effectively migrate to WebSphere Application Server V7.0 through V8.5.5, whether from a previous version of WebSphere Application Server or competitive application servers including Apache Tomcat Server, JBoss Application Server, Oracle® Application Server, and Oracle WebLogic Server.

Do you want to scan application binaries? Check out the newest tool, the Migration Toolkit for Application Binaries (currently in Tech Preview).This new command-line tool, you can quickly evaluate application binaries for rapid deployment on the WebSphere Application Server Liberty profile. https://developer.ibm.com/wasdev/docs/migration-toolkit-application-binaries-tech-preview/

Also there is a migration toolkit dedicated to move Was Full Profiles to WAS Liberty Profile.

The WebSphere Version to Version Application Migration Tool enables organizations deploying WebSphere Application Server V7 through V8.5.5 to more easily migrate applications from WebSphere Application Server V5.1 through V8. Upgrading to a more recent version of WebSphere Application Server is of course less time-consuming than migrating from another application server, given that IBM has made significant investments in upward compatibility, configuration, and management process upgrades, as well as API preservation and consistency between versions. However, in some cases, applications must be changed in order to support or exploit new levels of industry standard specifications delivered with new versions of WebSphere Application Server. These toolkits can be located at https://developer.ibm.com/wasdev/downloads/#filter/sortby=lastUpdatedOn;sortorder=desc;q=migration%20toolkit

The Application migration tool is available as eclipse feature and can be installed into eclipse version 3.5 or higher. This toolkit can also be installed in Rational Application Developer version 7.5 to 8.5. This tool is a rule based code analyzer and when run against an eclipse project, can identify issues that can impact migration of the application to the newer version of WAS. The tool also can automatically fix certain types of issues. With the help of this tool, one case migrate applications to the newer JEE specification very quickly, and easily identify and implement any application changes required when upgrading to WebSphere Application Server V7 through V8.5.5.

The migration wizard can also deploy the applications as it is in the new application server, but this may not work in many cases, and as mentioned above there is a separate Application Migration Tool.

IBM are very hot on providing tools. Not only for their own consulting use but for their clients and the industry. It is important to note that with IBM there is often more than one way to skin a cat, we are often spoiled for choice, so this is why this guide was created. My intention in my courses and consutling, is to explain by example the intricacies of the different tools available and their typical use-cases.
