Deprecated and Discontinued Features

This page provides information on deprecated and discontinued features.

About Deprecated and Discontinued Technologies and Features

From time to time, InterSystems stops further development of a technology when newer and better options are available. However, product support for these capabilities continues in the same way that it does for products beyond our Minimum Supported VersionOpens in a new tab.

Deprecated designates a feature or technology that InterSystems no longer actively develops and for which better options exist. Deprecated items should not be used for new development. The deprecated designation indicates that customers should plan to eliminate use of the feature or technology. InterSystems maintains the staff expertise to support deprecated product capabilities.

Discontinued designates a feature or technology that is no longer viable for use, even in existing applications. InterSystems feels that continued use of such technology is a risk for our customers. The reasons for this include but are not limited to:

Usage has declined to a small number of customers.
The feature has become incompatible with current technologies or security practice.
Incompatibilities between the feature or technology and our current product implementation make application maintenance prohibitive.
The feature or technology depends on discontinued content from a third party.

Unstructured Information Management Architecture (UIMA) Integration

As of version 2026.2, the capability to implement the Unstructured Information Management Architecture (UIMA) has been removed and can no longer be used. This feature had been deprecated in 2023.1.

InterSystems Cloud Manager

As of version 2025.3, InterSystems Cloud Manager (ICM) has been removed and will not be supported in subsequent releases.

Customers in the cloud who are interested in deploying and managing an InterSystems IRIS deployment with many systems should use Kubernetes and the InterSystems Kubernetes Operator, which has similar functionality to ICM.

MultiValue

As of version 2025.1, MultiValue is deprecated. InterSystems will continue to support existing customers using the technology, but it is not recommended for new applications. Support will continue to be available from the Worldwide Response CenterOpens in a new tab on the same “best effort” basis as is provided for releases older than Minimum Supported VersionsOpens in a new tab.

While there are no immediate plans to remove MultiValue from our products, InterSystems reserves the right to remove the feature at a future date. If you have questions about your current or planned use of MultiValue, please reach out to your account team.

System Alerting and Monitoring

System Alerting and Monitoring (SAM) is discontinued. As of December 4, 2024, the container is no longer available for download. However, the OpenMetrics APIs are still supported.

Private Web Server (PWS)

As of version 2023.2, local installations of InterSystems IRIS will no longer install the private web server and InterSystems IRIS containers will no longer provide the private web server.

InterSystems strongly recommends that you install an external web server and configure it according to your needs, instead of using the private web server. Note that this is not a change in existing InterSystems recommendations and there is no change in the list of supported web servers.

Effective with the first EM release in 2026, the private web server will be discontinued; at that point, upgrades of existing InterSystems IRIS instances will remove the private web server.

For more details on this change, see the Private Web Server (PWS)Opens in a new tab topic in the 2023.2 new features listing.

Studio

As of version 2023.2, Studio has been deprecated. It is still included with this release, but it will be removed from a future release.

InterSystems recommends Visual Studio (VS) CodeOpens in a new tab with the InterSystems ObjectScript Extension PackOpens in a new tab, which provides a fully-featured integrated development environment for InterSystems applications. The InterSystems ObjectScript Expansion Pack includes the following extensions: InterSystems ObjectScriptOpens in a new tab, InterSystems Language ServerOpens in a new tab, and Server ManagerOpens in a new tab extensions. See the documentation for the InterSystems VS Code extensionsOpens in a new tab for information on migrating from IRIS Studio to VS CodeOpens in a new tab.

Spark Connector

As of version 2022.1, the Spark connector has been deprecated. As of version 2022.3, it has been discontinued. As of version 2023.1, it has been removed from releases.

Spark now has a built-in JDBC connector. If you use the Spark connector, you should modify your code to use the Spark JDBC connector.

Atelier

As of version 2021.1, Atelier has been deprecated.

Shadowing

As of version 2019.1, shadowing has been discontinued. Applications using shadowing should migrate to the corresponding capabilities available with mirroring, as described in the High Availability Guide.

Zen

As of version 2019.1, Zen has been deprecated. It is still included with this release, but it will be removed from a future release.

Zen Reports

As of version 2019.1, Zen Reports has been deprecated. It is still included with this release, but it will be removed from a future release.

ActiveX

As of version 2019.1, ActiveX is discontinued and is no longer viable for use in new or existing applications. For customers who have migrated from Caché or Ensemble, ActiveX is deprecated and these customers should plan to eliminate its use.

IntegratedML Providers

As of version 2025.1, the following machine learning providers for IntegratedML have been discontinued:

H2O
DataRobot

The Java libraries used by these providers are no longer shipped with InterSystems IRIS. If you require these libraries, you can copy the IRIS_HOME/dev/java/lib/1.8/intersystems-integratedml-2.x.x.jar file from an installed instance of InterSystems IRIS Machine Learning version 2024.1 (available on the WRC software distribution pageOpens in a new tab) to the corresponding location in your current InterSystems IRIS installation. InterSystems recommends migrating your models to the InterSystems-provided AutoML provider, which remains fully supported. To migrate to AutoML, mark it as your default ML configuration and retrain your models:

SET ML CONFIGURATION %AutoML; 
TRAIN MODEL MyModel;
