Deprecated, stabilized, and removed features
If you are migrating from an earlier release of WAS, you should be aware of the various features that have been deprecated, stabilized, and removed since v6.x.
This topic is about configuration migration, such as migrating dmgrs and federated nodes in a network deployment environment. The Application Migration Toolkit for WAS provides support for migrating applications from previous versions of WAS to the latest product version. For information about migrating applications, read more about the Application Migration Toolkit.

If a feature is listed as deprecated, IBM might remove this capability in a subsequent release of the product. Future investment will be focused on the strategic function listed under "Recommended Migration Actions" in Deprecated features. Typically, a feature is not removed until at least two major releases or three full years (whichever time period is longer) after the release in which that feature is deprecated. For example, features that are deprecated in v6.0, v6.0.1, or v6.0.2 are not removed from the product until after v7.0 because both Version 6.0.x and v6.1.x are major releases. In rare cases, it might become necessary to remove features sooner; such cases are indicated clearly and explicitly in the descriptions of these deprecated features.
For information on features that have been deprecated in this and earlier releases of WAS, read Deprecated features.
If a feature is listed as stabilized, IBM does not currently plan to deprecate or remove this capability in a subsequent release of the product; but future investment will be focused on the alternative function listed under "Strategic Alternative" in Stabilized features. You do not need to change any of your existing applications and scripts that use a stabilized function; but you should consider using the strategic alternative for new applications.
For information on features that have been stabilized in this release of WAS, read Stabilized features.
For information on features that have been removed in this and earlier releases of WAS, read Removed features.
