Step 1: Disabling System Replication

You can disable SAP HANA system replication for an SAP HANA system by first unregistering the secondary system and then disabling system replication on the primary system.

Before we begin to disable system replication, ensure that the Secondary System has been stopped, and that the Primary System is online.

First, we will unregister the secondary system.
In the Systems Panel, right-click the Primary System and choose Configuration and Monitoring > Configure System Replication.

Configure System Replication

In the pop-up dialog, select Unregister secondary system and then Next.

Unregister Secondary System

Select the Secondary System Name. Since Dynamic Tiering only support two-tier system replication, you can leave the default option. Click Next.

Select Secondary System

Review the configuration details and click Finish.

Review configuration details

Now, to disable system replication on the primary system, right-click the Primary System again, and choose Configuration and Monitoring > Configure System Replication.

Configure System Replication

Choose Disable system replication and click Next.

Disable System Replication

Leave the Ignore secondary system unchecked, which will remove all secondary system’s metadata, and click Finish.

Ignore Secondary System

System Replication has now been disabled.
