Migration considerations, WebSphere Adapter for JD Edwards EnterpriseOne

WebSphere® Adapter for JD Edwards EnterpriseOne version 7.5.0.2 may have some features and updates that might affect your existing adapter applications. Before migrating applications that use WebSphere Adapter for JD Edwards EnterpriseOne, you must consider some factors that might affect your existing applications.

Compatibility with earlier versions

WebSphere Adapter for JD Edwards EnterpriseOne version 7.5.0.2 is fully compatible with the custom business objects (XSD files) and data bindings that are created using the adapter version 6.1.x, version 6.2.x, version 7.0.x, version 7.5.0, and version 7.5.0.1 and enables the existing business objects and data bindings to work well in the latest version of the adapter.

Because version 7.5.0.2 of WebSphere Adapter for JD Edwards EnterpriseOne is fully compatible with version 6.1.x, version 6.2.x, version 7.0.x, version 7.5.0, and version 7.5.0.1, any of your applications that used previous versions of WebSphere Adapter for JD Edwards EnterpriseOne run unchanged when you upgrade to version 7.5.0.2. However, if you want your applications to use features and functionality present in version 7.5.0.2 of the adapter, perform the migration of the artifacts as well as the upgrade of the adapter.

The migration wizard replaces (upgrades) version 6.1.x, version 6.2.x, version 7.0.x, version 7.5.0, or version 7.5.0.1 of the adapter with version 7.5.0.2 and enables version 7.5.0.2 features and functionality for use with your applications.

Note: The migration wizard does not create components or modify existing components, such as mappers and mediators to work with version 7.5.0.2 of the adapters. If any of your applications embed an adapter that is version 7.5.0.1 or earlier and you are upgrading to version 7.5.0.2, and you want your applications to take advantage of the features and functions in version 7.5.0.2, you might need to change those applications.

If the artifacts within a module have inconsistent versions, the entire module is marked as unavailable for migration and cannot be selected. Version inconsistencies are recorded in the workspace log, as they indicate that a project might be corrupted.

The adapter migration wizard in IBM® Integration Designer Version 8.0 only supports the migration of adapters from version 6.1.x, version 6.2.x, version 7.0.x, version 7.5.0, and version 7.5.0.1 to version 7.5.0.2. It does not support the adapter migration from lower versions to any of the versions before version 7.5.0.2.

Deciding whether to upgrade or to upgrade and migrate

The default processing of the migration wizard is to perform an upgrade of the adapter and to migrate the application artifacts so that the applications can use features and functions in version 7.5.0.2 of the adapter. When you choose to upgrade the adapter by selecting a project, the wizard automatically selects the associated artifacts for migration.

If you decide that you want to upgrade the adapter from version 6.1.x, version 6.2.x, version 7.0.x, version 7.5.0, or version 7.5.0.1 to version 7.5.0.2, but you do not want to migrate the adapter artifacts, you can do so by clearing the adapter artifacts from the appropriate area of the migration wizard.

Running the migration wizard without selecting any adapter artifacts installs and upgrades your adapter. As the artifacts are not migrated, your applications cannot take advantage of the features and capabilities that exist in version 7.5.0.2 of the adapter.

Migrating multiple adapters referred within a project

When a module contains one or more connector projects, each of which references to different adapters (for example, a module project that contains connector projects referring to JDBC and SAP adapters), the migration wizard identifies the artifacts belonging to each adapter and migrates these artifacts without disrupting the artifacts of other adapters.

When you select the module project and launch the migration wizard:

The Source connector field lists the connector projects with the selected module project.
The Dependent artifact projects area lists only the selected module project.

If you select the connector project and launch the migration wizard:

The Source connector field lists only the selected connector project.
The Dependent artifact projects area lists all projects which reference the selected connector project, including the module project.

Run the migration wizard in a test environment

Because adapter migration might require you to change those applications that use version 7.5.0.2 of WebSphere Adapter for JD Edwards EnterpriseOne, you must always perform the migration in a development environment first and test your applications before deploying the application to a production environment.

The migration wizard is fully integrated with the development environment.

Deprecated features

Become familiar with the deprecated features in version 7.5.0.1 and make any required changes to your applications.

A deprecated feature is one that is supported but no longer recommended and that might become obsolete. The following features from earlier versions of WebSphere Adapter for JD Edwards EnterpriseOne have been deprecated in version 7.5.0.1 and might require changes to your applications:

In version 7.5.0.1, the Timeout property moved from a Resource Adapter property to a Managed Connection Factory (J2C) property. In order provide compatibility with earlier version with artifacts that were generated with the Timeout property set as a Resource Adapter property (version 6.2.x), the Adapter for JD Edwards EnterpriseOne, version 6.2.x behaves as follows:
1. The adapter looks for the Timeout property setting in the Managed Connection Factory (J2C) properties.
2. If the Timeout property is not set as a Managed Connection Factory (J2C) property, the adapter looks for it in the Resource Adapter properties.
3. If the Timeout property is not set as either a Managed Connection Factory property or a Resource Adapter property, the adapter assigns the default setting for the Timeout property of 30 seconds.
