Upgrading Database on Source Location

This section provides step-by-step instructions for upgrading a source database in a channel with activated replication to ensure that no data is lost during the upgrade.

Upgrade Steps

1. Stop your application that is making changes to the database.

2. Ensure all changes made by the application are captured, and wait for the replication latency to reach zero. For more information on monitoring the replication latency, refer to the Statistics page.

3. Suspend the capture and integrate jobs running in a channel.
