What is required to convert an SAP HANA 1.0 single database system to an SAP HANA 2.0 multitenant database system?

To convert an SAP HANA 1.0 single database system to an SAP HANA 2.0 multitenant database system, an upgrade of the existing SAP HANA database system is essential. The upgrade process transitions the database from the earlier version to the latest version, enabling the new features and capabilities introduced in SAP HANA 2.0, such as multitenancy.

Multitenant database containers (MDC) provide a more flexible and efficient way to manage multiple databases within a single database system. As part of the upgrade, the database is transformed to support this architecture, allowing for better resource utilization and improved management of various data instances.

This upgrade is a critical step because it not only brings the system to a supported version but also ensures that the new features that enhance performance and scalability are implemented correctly, bridging the gap between the different versions and their respective capabilities.

Other options like downgrading or switching to a different database system do not facilitate the upgrade path needed for converting a single database system into a multitenant one. Reinstalling the database may not necessarily include the upgrade process that is critical for enabling multitenancy features.
