The WebSphere Message Broker (hereafter called WMB) / IBM Integration Bus (hereafter called IIB) Dynamic Migration Guide is designed to help users choose, plan and simplify the process of migrating from an older version to a more current version of WMB/IIB.
The guide is broken down into the following sections:
– Planning your Migration
– Determine your migration path
– Preparing for your migration
– Executing your migration
– Supplemental Resources
– Case Studies
Each section helps you walk through a migration and you can choose the appropriate entry point depending on your experience with the migration process. Click on IIB Dynamic Migration Guide to invoke it in your web browser or download the pdf Dynamic_migration_guide here.
This section contains guidelines and references to help you check Pre-reqs for your planned target version to ensure compatibility. As shown in Figure 1, this section allows you to check pre-requisites which are specific to Message Broker as well as other related IBM products for your potential target IIB/WMB version. This step is critical to ensure overall compatibility and support when determining which version to migrate to.
As shown in Figure 2, to determine your migration path you should always check the product documentation of the release to which you plan to migration:
– The What’s new section provides details of the new features added to each release
– The Planning section provides details of what you need to take into account during the migration process
– Potential Impact section covers the major impacts you may face during a migration. This will depend on the features you have used in your current implementations.
The outcome of this step is to help you find specific features available in these releases and assist to make the decisions required during a migration.
As shown in Figure 3, this section details the migration options and considerations for each of the options, as well as explanation of the differences between In-Place and Parallel migration methods as it relates to IIB.
Once you have decided what target version you will be migrating to and planned for the migration option, you can review this section for executing your migration. As shown in Figure 4, this section lists the tasks of installation and executing the migration option.
Task 1- Installing the Chosen Product Version
This section will guide you through the process of downloading and installation of target version including the verification of the installation.
Task 2a – Parallel Migration
Parallel migration allows you to go through the migration process without any downtime on the existing Broker. This section provides instructions to perform parallel migration for each target version.
Task 2b – In-Place Migration
In-Place migration is a method of migrating the same broker from source to target version (via a command). As seen in Figure 7, this section would take you through the steps needed to complete an in-place migration to your specific target version in both stand-alone and Multi-Instance environments.
Task 2c â€“ Migrating Development Resources
This section will guide you through the migration processes for your development resources depending on the version you plan to migrate to.
The supplemental resources section contains resource links for existing content relevant to planning, installation and migration (Webcasts, FAQs, technical library) as well as social forums to connect with the experts on these subjects (Integration community, dwAnswers). This also includes a compilation of all the resources provided through the entirety of this guide into a single pdf file (Other resources) for your convenience. See Figure 8 below.
The Migration guide is built to walk the users step by step through the WMB/IIB migration process, from planning to execution. The guide also contains a list of useful links and resources that migration users would typically need to follow, regardless of any environment distinction.
