Show full answer Show less Before upgrading, review pre- and post-upgrade tasks to ensure smooth transition and accurate data management performance. ## Key Features * **Data Management Console Enhancements:** * Yokohama introduced a console to summarize storage consumption and manage data growth on your instance. * Zurich expands this with the ability to monitor data usage at the table level, including associated tables for attachments, audit records, and journal entries. * Support for logical tables such as Incident, Problem, and Change Request has been added to provide holistic data usage insights. * Identification of tables that drive the most data growth in related tables helps focus cleanup efforts. * Rule summary features allow tracking of record backlogs and execution history of data management rules per table. * **Table Cleaner Improvements:** Scalable automatic deletion of older or unwanted records was introduced in Yokohama to help manage data retention efficiently. ## Key Changes * **Interface and Theme Updates:** Zurich adopts the Coral theme as default for portals, web, and mobile experiences, offering a fresh, brand-neutral look and a dark theme option to improve user experience and accessibility. * **Navigation:** In Yokohama, the Data Management Console is accessed via *All \> System Data Management \> Data Management Console*. ## Deprecations and Removals * The Data Usage Visualization Console dashboard was deprecated in Zurich, with the Data Management Console replacing it for monitoring data growth. * No features were removed in either Yokohama or Zurich releases. ## Upgrade Considerations * After upgrading a self-hosted instance to Yokohama, the `sysphysicaltablestats` table may not display up-to-date size data. To resolve this, enable the system property `com.glide.stats.storagediskusage.informationschema` to allow accurate database statistics collection. * Data management policy records are automatically created for tables with existing archive or table cleaner rules during upgrade. ## Activation and Additional Information * Data Management is active by default in both Yokohama and Zurich as part of the ServiceNow AI Platform capabilities. * No additional browser or localization requirements were introduced in these releases. * Accessibility improvements include the availability of a dark theme option in Zurich to reduce eye strain and enhance readability. ## Practical Benefits for ServiceNow Customers Upgrading to Zurich enhances your ability to monitor and manage data growth with more granular visibility at both logical and individual table levels. The improved Data Management Console and scalable table cleaner enable proactive data retention management, optimizing storage and system performance.

To see the correct table size, you can set the com.glide.stats.storage_disk_usage.information_schema system property to true, which allows the statsGatherer job to use the information schema to generate the required database statistics. * A data management policy record is automatically created for each table that is configured with an archive rule or a table cleaner rule prior to the upgrade. | | Zurich | No updates for this release. | [ ] ## New features Between your current release family and Zurich, new features were introduced for Data Management. {#dfrn3-datamanagement-summary__entry__8} | Release | Release notes | |-|-| | Yokohama | [Data Management Console](https://www.servicenow.com/docs/access?context=viewing-data-usage&family=yokohama&ft:locale=en-US) : View a summary of storage consumption on your instance and manage the growth of data directly from the Data Management Console.
