Upgrade without restart

[Meinrad]

Hi,

there are several statements in the material of Learning Journey about upgrade of HANA Database and mandatory restart.

Well, in the customizing I found this switch

An I think it works - at least for one of the last patches. There was no restart.
So let me please ask for details on that topic.
Kind Regards

@Meinrad This feature came after the course materials were published, so in the next publishing round it will be added and explained.

For the time being, the feature "Upgrade without a restart" does exactly what it promises.

The "Upgrade without a restart" first creates a replica on the upgraded release, then makes sure the systems are insync, the performs a take-over to the replica.

It's like the near zero downtime upgrade you can perform in an on-premises SAP HANA database with system replication. Or if you would think more in a multitenant setup, a tenant move using tenant replication.
