## Important Upgrade Information

* **Performance Improvements:** Starting from Yokohama and Zurich releases, upgrading legacy replication sets to V2 is essential. V2 uses Hermes Messaging Service, significantly improving performance and processing efficiency.
* **Log Rotation:** From Yokohama onwards, log rotation is automatically enabled for the Replication Payload Error table after upgrade with a default schedule of seven shards, each covering five days. Pre-upgrade logs are truncated automatically.

## New Features

* **Yokohama:**
  * Scheduled seeding to replicate data at specific times daily.
  * Support for multiple concurrent seeding requests---one active per replication set.
  * Automatic seeding of missing or mismatched records during data comparison requests.
* **Zurich:**
  * Enhanced monitoring with IDR Monitoring Dashboard for scheduled replication sets.
  * Ability to track scheduled replication requests via a related list.
* **Australia:**
  * Redesigned IDR Diagnostics page providing detailed test descriptions and results.

## Changes to Existing Features

* **Yokohama:**
  * Unlimited record counts in seeding requests and data comparisons for V2 replication sets.
  * Inclusion of attachments in data comparison requests.
  * Optimized seeding throughput and message queue efficiency.
* **Zurich:**
  * Introduction of the Coral theme as default for portals and experiences with Next Experience or Core UI enabled, including a dark theme option to improve usability.
* **Australia:** No changes recorded.

## Deprecations and Removals

* **Yokohama to Zurich:** Legacy replication sets were deprecated and ultimately unsupported; customers must upgrade to V2 to maintain replication.
* **Zurich:** Removal of Key Management Service and VAULT Service Status tests from the IDR Diagnostics page.
* **Australia:** No further deprecations or removals.

## Activation and Subscription

Instance Data Replication is a ServiceNow AI Platform feature requiring activation of the IDR (com.glide.idr) plugin and a separate subscription in all releases from Yokohama through Australia.

## Additional Notes

* **Accessibility:** The introduction of the Coral theme includes a dark mode for web and mobile to reduce eye strain and improve readability.
* **Browser, Localization, and Additional Requirements:** No new or changed requirements across the releases.

## Practical Benefits for ServiceNow Customers

* Enhanced replication performance and efficiency through V2 upgrade.
* Improved monitoring and management of replication processes via dashboards and related lists.
* Greater flexibility and automation in seeding and data comparison, including handling of attachments.
* Streamlined log management with automated log rotation to maintain system health.
* Access to detailed diagnostics facilitating better troubleshooting.
* Modernized user experience with the Coral theme and dark mode support.
