SAP HANA Cloud Database Upgrades and Patches – Part 1
In this blog, will provide you more information about SAP HANA Cloud Upgrade and Patches processes for customers, partners and every individual database adminstrators to initiate by our own maintenance window.
Upgrades and patches for the SAP HANA database are continuously provided.
Patches are provided for every version of the SAP HANA database for up to seven months after its initial release. Apply a patch to fix known bugs and benefit from other improvements.
By default, applying a patch requires the instance to be restarted, which causes downtime. To reduce the downtime, an upgrade can be performed without the need to restart the instance. You can choose whether the instance is restarted or not in the instance configuration under Advanced Settings Upgrade Mode.
If a new version of the SAP HANA database is available, then a notification appears in SAP HANA Cloud Central.
A new version of SAP HANA Cloud is released every three months. The version is referred to by QRC (quarterly release cycle), the quarter and the year in which it was released, for example QRC 1/2021. In between QRC releases, patches that contain bug fixes and other improvements are made available.You cannot downgrade to a lower version or revert to the previous version after the upgrade was performed.
The currently installed version of the SAP HANA database and its version history are available on the instance configuration page under Version.

By default, an upgrade to a newer version of the SAP HANA database requires the instance to be restarted, which causes downtime. To reduce the downtime, an upgrade can be performed without the need to restart the instance. If you change the upgrade mode from Upgrade with restart to Upgrade without restart, a replica of database instance is created. When initiating an upgrade, the replica is upgraded first and becomes the active instance once the upgrade is complete.
To change the Upgrade Mode, navigate to the Advanced Settings in the instance configuration and will be continued in next blog – Part 2

Thank you for putting together this series of blog posts.
Perhaps you can edit this post as it suggest that covers the upgrade & patches for SAP HANA Cloud but it only does it for one of its components.
