Deprecated features

If a feature is listed as deprecated, or certain system requirements are indicated as deprecated on the Software Product Compatibility Reports website, IBM might remove this capability or support in a subsequent release of the product. IBM can focus on follow-on technologies or the strategic feature that is listed under Action. Typically, a feature is not deprecated unless an equivalent alternative is provided or available. A feature is not removed for at least two releases after the deprecation of the feature is declared. In rare cases, it might be necessary to remove features sooner; such cases are indicated in the descriptions of these removed features.

The following features from previous releases are deprecated in IBM Business Automation Workflow versions 22.0.1 and 22.0.2.

Table 1. Deprecated features for Business Automation Workflow 22.0.1 and 22.0.2
Deprecated features	Description	Action
22.0.2 Use of an external Elasticsearch 7.x cluster by Process Federation Server	Use of an external Elasticsearch 7.x cluster with Process Federation Server is deprecated. An external Elasticsearch 8.x cluster must be used instead.	Upgrade your existing Elasticsearch 7.x to version 8.x or configure Process Federation Server to use a new Elasticsearch 8.x cluster.
22.0.2 Process Center Sharing	When you register two Process Centers with each other, you can share toolkits with other users, or subscribe to toolkits that other users share.	In Workflow Center, there is no equivalent function.
22.0.2 Process Center Governance	In Process Center, you can apply for a governance process that provides control over the installation of process applications or notifies people when a snapshot is installed or changes status.	In Workflow Center, there is no equivalent function.
22.0.2 Process Center Documents	In Process Center, you can generate process documentation for Process Apps or single BPDs.	In Workflow Center, there is no equivalent function.

22.0.2 Business Automation Workflow Web Service APIs	The web API allows handling of process instances and tasks from an external web service client.	Use Business Automation Workflow REST runtime API instead, see Workflow REST API programming.
