What are the mandatory prerequisites before activating SAP HANA system replication with read-enabled mode?

The prerequisite for activating SAP HANA system replication with read-enabled mode is that both systems must have the same SAP HANA version. This is crucial for ensuring compatibility and proper functioning between the primary and secondary systems. When the versions match, the replication process can take place smoothly without any discrepancies in functionality or data handling.

Both systems having the same version guarantees that features, optimizations, and data types are consistent across the environments, reducing the risk of errors during replication and ensuring that queries executed in read-enabled mode can access resources without encountering compatibility issues.

While the other options may relate to general good practice or specific circumstances within system replication, they are not mandatory for the activation of read-enabled mode. Therefore, ensuring version consistency is the essential requirement for successful activation in this context.
