-   **[Explore](https://www.servicenow.com/docs/access?context=exploring-sandboxes&family=zurich&ft:locale=en-US)**

View the total, available, and allocated sandboxes in your instance by using the Sandbox Management home dashboard. The dashboard also displays information about each sandbox, including the status, data utilization, owner, when the sandbox was last accessed, and when the sandbox was allocated.

-   **[Using sandbox templates](https://www.servicenow.com/docs/access?context=create-sandbox-template&family=zurich&ft:locale=en-US)**

Enable your delegated developers to reuse the data so that they can test their changes without manually inputting the data every time.

-   **[Create a Data Generation Profile](https://www.servicenow.com/docs/access?context=create-data-generation-profile&family=zurich&ft:locale=en-US)**

Enable your customers to generate the data for testing within the context of developer sandboxes, but also independently of sandboxes.

**Note:** Developer Sandboxes can't copy all the instance data. Data generation profiles enable a statistical sampling of data from selected tables with curated mappings to populate the sandbox with the data needed for building an application.

-   **[Allocate a sandbox](https://www.servicenow.com/docs/access?context=allocating-sandboxes&family=zurich&ft:locale=en-US)**

Allocate the sandboxes that were created to your development teams.

-   **[Retire sandboxes](https://www.servicenow.com/docs/access?context=retire-sandboxes&family=zurich&ft:locale=en-US)**

Retire outdated sandboxes to make room for the new sandboxes in your instance.

-   **[Automatically backed up update sets](https://www.servicenow.com/docs/access?context=dev-sbx-clone-upgrade-info&family=zurich&ft:locale=en-US)**

If you install Developer Sandboxes on an instance after Zurich Patch 5, update sets are automatically backed up when the instance is upgraded.


</td></tr><tr><td>

Australia

</td><td>

-   **[New granular roles for administration](https://www.servicenow.com/docs/access?context=dsb-installed-with&family=australia&ft:locale=en-US)**

Several new granular roles enable developers to complete administrative and configuration tasks without requiring the full admin role.

-   **[Support for separate indices for AI Search](https://www.servicenow.com/docs/access?context=exploring-sandboxes&family=australia&ft:locale=en-US)**

AI Search \(AIS\) now maintains separate indices for each sandbox environment, ensuring development activities that rely on AIS are correctly supported.

**Note:** The AIS integration with Developer Sandboxes is supported only on non-production environments.


</td></tr><tr><td>

Brazil

</td><td>

-   **[Fully automated setup with self-serve license assignment](https://www.servicenow.com/docs/access?context=dsb-license-allocation-about&family=brazil&ft:locale=en-US)**

Assign purchased sandbox packs to non-production instances directly from the **Developer Sandbox Management** tab in App Engine Management Center \(AEMC\), without opening a support case. Install the new licensing plugin on your license management instance, install the sandbox plugin on your non-production instances, and use the license management UI on the controller instance to distribute packs. Each pack provides 10 sandboxes, and you can assign a maximum of 3 packs to a single non-production instance.

In support, the following have been added when the new com.glide.dsb.licensing plugin is installed:

    -   A new instance allocation table \[sys\_dsb\_instance\_allocation\] is now installed with Developer Sandboxes.
    -   The new sandbox admin role \(`sn_dsb_commons.sandbox_license_admin`\) lets users distribute sandbox packs to non-production instances without full admin access.
-   **[Four free sandbox licenses](https://www.servicenow.com/docs/access?context=dev-sbx-entitlements&family=brazil&ft:locale=en-US)**

All instances now get four free sandboxes per non-production instance to try out Developer Sandboxes. You can use the four free licenses on the same instance as purchased sandboxes, for a maximum of 34 sandboxes on an instance.


 -   **[Sandbox pooling for faster provisioning](https://www.servicenow.com/docs/access?context=allocating-sandboxes&family=brazil&ft:locale=en-US)**

Allocate sandboxes faster using pre-pooled instances. When you allocate a sandbox, you claim one from a pre-created pool rather than waiting for a new instance to be provisioned. Sandbox URLs are randomly generated strings and no longer match the sandbox display name. The display name remains configurable, but you can't change the URL.

**Note:** Because pooled sandboxes are precreated, they may be out of date from the current base instance state, but are refreshed every 24 hours.

-   **[Automatic update set sources](https://www.servicenow.com/docs/access?context=dsb-update-sets&family=brazil&ft:locale=en-US)**

Transfer update sets between production and sandbox instances without manual configuration. When a sandbox is created, an update set source pointing to the sandbox is automatically created on the base instance, and an update set source pointing to production is automatically created on the sandbox. When a sandbox is retired, both update set sources are automatically removed.

 -   **[Schema change for shared tables isolates the table](https://www.servicenow.com/docs/access?context=dsb-installed-with&family=australia&ft:locale=en-US)**

To ensure configuration consistency, if you make a schema change, such as adding a column, to a shared table, the table now becomes an isolated table on the sandbox that initiated the schema change.


 -   **[Upgrade enhancements](https://www.servicenow.com/docs/access?context=dev-sbx-clone-upgrade-info&family=australia&ft:locale=en-US)**

After an upgrade, Developer Sandboxes now recreates the sandboxes on an instance and automatically backs up update sets to the base instance.

An error status message now appears on the instance home page when there’s an initialization error when allocating a sandbox.

Starting with the Brazil Patch 2 release, installing the `com.glide.dsb` plugin no longer enables Developer Sandboxes automatically. Enable it manually by setting the following property on the instance before you add it through license management:

    -   `glide.dev_sandbox.enabled`: Set to `true`.

-   Work in fully isolated environments, so changes in one sandbox don't affect teammates, the baseline instance, or other sandboxes running in parallel.
-   Provision sandboxes on demand and align them to specific stories, developers, or test plans, enabling multiple workstreams to run concurrently without waiting for shared resources.
-   Integrate with source control \(Git\), reducing merge conflicts and making co-development smoother compared to shared development instances.
-   Safely test configurations, workflows, and integrations within your own sandbox before promoting changes, reducing rework and protecting system stability.
