New tenant for HANA database in a system replication

Hello, I have two HANA (2.0sp3) database in a system replication. I need to install a new system with a new tenant from a Homogeneous System copy. I am checking this chapter in SAP HANA Administration Guide https://help.sap.com/viewer/6b94445c94ae495c83a19646e7c3fd56/2.0.03/en-US/d20e1a973df9462fa92149f29ee2c455.html But I don't find a clear answer about this procedure

This algorithm is correct?

1. Stop the Secondary HANA system
2. Unregister the Secondary system (stop replication)
3. Install a new database instance for a new system in the Primary system from a Homogeneous System copy (backup-restore).

4. Register the Secondary system with options - Initiate Data shipping - yes, start the Secondary system after registration - checked.

Thank you for answer!
