Show full answer Show less ## Key Features * **Sandbox Management Home Dashboard:** In Zurich, you can monitor your sandboxes more effectively by viewing total, available, and allocated sandboxes within your instance. The dashboard also displays detailed sandbox information such as status, data utilization, owner, last accessed date, and allocation date. * **Sandbox Templates and Data Generation Profiles:** Delegated developers can reuse data through sandbox templates, enabling efficient testing without manual data entry. Data Generation Profiles allow customers to generate testing data within or independently of sandboxes by statistically sampling data from selected tables with curated mappings. Note that Developer Sandboxes cannot copy all instance data, making data generation essential for populating sandboxes appropriately. * **Sandbox Lifecycle Management:** You can allocate sandboxes to development teams and retire outdated sandboxes to optimize sandbox availability in your instance. * **Automatic Backup of Update Sets:** For instances upgraded after Zurich Patch 5, update sets are automatically backed up, improving upgrade reliability and data protection. * **Support for Build Agent in Sandboxes:** This feature enables administrators and delegated developers to request, access, and manage isolated development environments on the same underlying instance, enhancing developer isolation and parallel development capabilities. ## Key Changes * **Upgrade Enhancements:** Automatic backups during upgrades function correctly in Zurich, addressing previously reported issues. * **Data Generation Deprecation:** All data generation metadata and non-metadata records are automatically deleted. The data generation plugin is no longer discoverable, and references to data generation have been removed from sandbox templates. Sandbox initialization now operates independently from data generation logic. ## Activation and Additional Information * **Activation:** Developer Sandboxes are available through the ServiceNow Store. Customers should contact their ServiceNow account manager to install and activate Developer Sandboxes. * **No Updates:** There are no changes or updates related to browser requirements, accessibility, localization, or additional requirements in this upgrade. ## Practical Implications for ServiceNow Customers With the Zurich release, you can expect improved management and visibility of Developer Sandboxes, streamlined data reuse and generation capabilities, and enhanced sandbox lifecycle controls. The automatic backup of update sets during upgrades reduces risk, while the Build Agent support offers better developer isolation and parallel development efficiency. Be aware of the deprecation of data generation components, which means sandbox initialization no longer depends on these features. To capitalize on these improvements, ensure you complete all pre- and post-upgrade tasks, engage with your ServiceNow account manager for activation, and familiarize your development teams with the new sandbox management tools.
