It highlights upgrade preparation tasks, new features, changes, deprecations, and activation details to ensure smooth transitions and improved data replication performance and monitoring. Show full answer Show less ## Important Upgrade Information * **Performance Improvements:** Upgrading replication sets to V2, which utilizes Hermes Messaging Service, enhances performance and processing efficiency. This upgrade is critical for customers moving from Yokohama and Zurich releases. * **Log Rotation:** Post-upgrade, log rotation is automatically enabled for the Replication Payload Error \[idrreplicationpayloaderror\] table. The default schedule divides logs into seven shards, each retained for five days, with pre-upgrade log entries truncated automatically. ## New Features * **Scheduled Seeding (Yokohama):** Allows scheduling of data replication from producer to consumer instances at specified times daily. * **Concurrent Seeding Requests (Yokohama):** Supports running multiple seeding requests simultaneously across different replication sets, with one active request per set. * **Automatic Seeding of Missing or Mismatched Records (Yokohama):** Enables automatic seeding when creating data comparison requests. * **Replication Monitoring (Zurich):** Provides progress tracking for scheduled replication sets and requests via the IDR Monitoring Dashboard and related lists. * **IDR Diagnostics Enhancements (Australia):** Offers a redesigned diagnostics page with detailed test descriptions and results to facilitate troubleshooting. ## Changes to Existing Features * **Seeding and Data Comparison Improvements (Yokohama):** Unlimited record counts in seeding requests and data comparisons for V2 replication sets; attachments now included in data comparison requests. * **Performance Optimizations (Yokohama):** Enhanced seeding throughput and message queue efficiency. * **UI Updates (Zurich):** Introduction of the Coral theme as the default for portals, web, and mobile with a dark theme option available to improve user experience. * **Australia Release:** No changes reported. ## Deprecations and Removed Features * **Legacy Replication Sets:** Planned for deprecation in Zurich; upgrading to V2 replication sets is mandatory for ongoing support and functionality. * **Diagnostics Tests Removed (Zurich):** Key Management Service and VAULT Service Status tests were removed from the IDR Diagnostics page. * **No removals or further deprecations in Australia release.** ## Activation and Subscription Instance Data Replication is a feature of the ServiceNow AI Platform that requires activation of the IDR plugin (com.glide.idr). Activation necessitates a separate subscription, consistent across Yokohama, Zurich, and Australia releases. ## Additional Notes * No updates to additional requirements, browser compatibility, or localization were introduced between Yokohama and Australia. * Accessibility improvements include the Coral theme's dark mode option introduced in Zurich to reduce eye strain. ## Practical Benefits for ServiceNow Customers * Enhanced efficiency and reliability of data replication through Hermes Messaging Service and V2 replication sets. * Improved monitoring and diagnostics capabilities for proactive replication management. * Greater flexibility with scheduling and concurrent data seeding, supporting large and frequently updated datasets. * Streamlined upgrade path by mandatory migration from legacy replication sets to V2, ensuring continued support and functionality. * Modernized user interface with accessibility options to enhance user experience across platforms.
