Migration overview

Migration refers to the steps used to preserve product configuration information and user applications from one product to another, or from one version of a product to another version of the same product. You must migrate your existing applications and configuration information from the previous product to WebSphere Process Server, or from the previous version of WebSphere Process Server to the newer version of WebSphere Process Server in order to use them in the new environment.

Migration steps can vary depending on the source or target of the migration. Typically, for minor version upgrades of a product such as from WebSphere Process Server 6.0.0 to WebSphere Process Server 6.0.1, there are no migration steps required besides installing the maintenance pack. This is because the upgrade is done "in place" to an existing installation, and the configuration and applications are preserved within the existing installation. Refer to Installing maintenance packages for information about installing such a maintenance pack. For migration from a previous product to WebSphere Process Server (for example, WebSphere InterChange Server to WebSphere Process Server) or across major versions of the same product (for example, WebSphere Business Integration Server Foundation to WebSphere Process Server), the migration steps include using migration tools to convert source artifacts to the new WebSphere Process Server version of the artifacts. The remainder of this topic describes migration from a previous product to WebSphere Process Server or across major versions of the same product. Again, for minor version upgrades refer to Installing maintenance packages.

WebSphere Process Server contains migration tools that assist in migrating existing application source artifacts into WebSphere Process Server artifacts. These tools can be accessed through the File->Import... wizards of WebSphere Integration Developer. The migration tools designed to assist with migration from WebSphere InterChange Server can also be accessed through the WebSphere Process Server migration wizard (accessible from the First Steps console) and command line of WebSphere Process Server. See the following links for information on using these tools.

Migration from another product to WebSphere Process Server is supported from the following predecessor products:

For more information on migration techniques, refer to the migration tutorials available at the IBM Education Assistant web site.

Note: Currently, there is no support in WebSphere Process Server similar to the upgrade support provided by the WASPreUpgrade and WASPostUpgrade commands in WebSphere Application Server. Migration from WebSphere Business Integration Server Foundation to WebSphere Process Server can be accomplished only through migration of the source artifacts (by hand and/or with assistance from the migration tools provided.) Existing WebSphere Business Integration Server Foundation configurations can be applied to WebSphere Process Server, but these configurations must be set up by hand. There is no automatic tool to migrate the configuration data.
Table 1. Overview of migration pathways
Migration pathway Description
WebSphere InterChange Server versions 4.2.0 or later.

Use either the Migration wizard from the WebSphere Process Server First Steps console or the resposMigrate command-line utility to migrate all WebSphere InterChange Server artifacts into WebSphere Process Server deployable artifacts, and optionally deploy them directly to WebSphere Process Server. For more information on the reposMigrate command-line utility, see Using the reposMigrate utility. Alternatively, you can use the Migration wizard from WebSphere Integration Developer to migrate all WebSphere InterChange Server artifacts into WebSphere Process Server deployable artifacts and place them into projects in the active WebSphere Integration Developer workspace.

See theWebSphere Integration Developer Information Center for details.
WebSphere InterChange Server versions 4.1.1 or earlier. You must first migrate to WebSphere InterChange Server version 4.2.0 or later.
WebSphere Business Integration Server Foundation versions 5.1 and 5.1.1. Use the Migration wizard from WebSphere Integration Developer to migrate WebSphere Application Server Developer Integration Edition service projects into projects in the active WebSphere Integration Developer workspace. See the WebSphere Integration Developer Information Center for details.
WebSphere MQ Workflow version 3.5. Use either the Migration wizard or the FDL2BPEL utility to migrate all WebSphere MQ Workflow artifacts into WebSphere Integration Developer deployable artifacts. See the WebSphere Integration Developer Information Center for details.
WebSphere MQ Workflow version 3.4 or earlier You must first migrate to WebSphere MQ Workflow version 3.5.
