# Assign Developer Sandboxes packs

# Assign Developer Sandboxes packs {#ariaid-title1}

Release version: Brazil  
Updated September 23, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Assign Developer Sandboxes packs to managed instances from the App Engine Management Center (AEMC).

## About this task

Developer Sandboxes are packaged in increments of 10, called packs. For more information about Developer Sandboxes entitlements and limits, see [Developer Sandboxes entitlements](https://www.servicenow.com/docs/wiC0SoH2gMseFyrWRfQkjg "Your company's entitlements determine whether you have access to Developer Sandboxes.").

## Before you begin

Warning:  
Developer Sandboxes pack assignments are permanent after they are submitted. Plan your sandbox pack assignment before you begin to avoid unintentional assignment.  
* The Developer Sandboxes Licensing plugin (com.glide.dsb.licensing) must be installed on your controller instance.
* The Developer Sandboxes plugin (com.glide.dsb) must be installed on the instances you want to assign Developer Sandboxes packs to.
* Multi-Instance Management is required for assigning Developer Sandboxes licenses. It depends on the Multi-Instance Setup app (`sn-app-amf`), which must be installed separately from the ServiceNow® Store. This app is not a dependency of the `com.glide.dsb.licensing` plugin and is not installed automatically. For details on adding managed instances, see [Connecting controller and managed instances](https://www.servicenow.com/docs/access?context=connecting-controller-managed-instances&version=brazil&pubname=brazil-platform-administration&ft:locale=en-US).

Role required: sn_dsb_commons.sandbox_license_admin or admin, plus app_engine_admin

## Procedure

1. Navigate to AllApp EngineAdministrationApp Engine Management Center.
2. Select the Developer Sandboxes page.  
3. Select Assign sandboxes.
4. In the Instance field, select the instance to assign Developer Sandboxes packs to.  
   Multi-Instance Management is required for assigning Developer Sandboxes licenses. It depends on the Multi-Instance Setup app (`sn-app-amf`), which must be installed separately from the ServiceNow® Store. This app is not a dependency of the `com.glide.dsb.licensing` plugin and is not installed automatically. For details on adding managed instances, see [Connecting controller and managed instances](https://www.servicenow.com/docs/access?context=connecting-controller-managed-instances&version=brazil&pubname=brazil-platform-administration&ft:locale=en-US).  
   The Assign sandboxes modal displays Ready by the instance name to indicate that the selected instance can be assigned sandboxes (has the prerequisite Developer Sandboxes required plugins installed and Multi-Instance Management configured). When an instance does not meet the requirements for sandbox assignment, an error message appears.

5. Select the plus icon ![]() to add packs or the minus icon ![]() to remove packs.  
   The maximum number of packs you can assign to an instance is 3 (30 sandboxes).
6. **Optional:** If a free pack is available, toggle on the switch to allocate the 4 free sandboxes to the selected instance.
7. Select the check box I understand that assignments are permanent.
8. Select Save.

For more information about Developer Sandboxes, see [Developer Sandboxes](https://www.servicenow.com/docs/4NKj2TtMxu0NBruxw~pxdA "Developer Sandboxes are isolated development environments on a shared instance. Delegated developers use them to build and merge changes in parallel, and admins request and manage them.").
