The ServiceNow® Instance Data Replication (IDR) application simplifies the data replication process between instances. Instance Data Replication was enhanced and updated in the Washington DC release.

Instance Data Replication highlights for the Washington DC release

  • Keep data synchronized by replicating data from your producer instance to one or more consumer instances across different departments and business units.
  • Maintain consistent data across different organizations in your company.
  • Easily update records that have different sys_ids on the producer and consumer instances.

See Instance Data Replication for more information.

Important information for upgrading Instance Data Replication to Washington DC

Improve the performance and processing efficiency of Instance Data Replication (IDR) by upgrading your replication sets to V2, which uses the Hermes Messaging Service. For details, see Upgrading legacy replication sets to V2 in Instance Data Replication.

Log rotation is automatically enabled for the Replication Payload Error [idr_replication_payload_error] table after the upgrade. By default, the log rotation schedule is comprised of seven shards, with five days for each shard. All log entries in this table created before the upgrade are automatically truncated.

Changed in this release

Hermes-only replication
Newly-created replication sets now use Hermes Messaging Service. You can no longer create legacy replication sets.
Comparing replicated data between instances
Compare data in replication sets with data transformations, bidirectional replication, and discrete replication.

Activation information
