    Important information for upgrading Instance Data Replication to Xanadu

    Before you upgrade to Xanadu, review these pre- and post-upgrade tasks and complete the tasks as needed.

    Release Release notes

    Vancouver

    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.

    If the Replication Payload Error [idr_replication_payload_error] table on your instance has more than 10 million records, set up table rotation according to KB1364728. Using table rotation to delete records from the Replication Payload Error [idr_replication_payload_error] table is safe because that table only contains replication errors logged by IDR and not any replicated data.

    Washington DC

    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.
