Hi Alberto,

It’s not possible to have different types of database configurations running within a single cluster.
So if the agents within a cluster are making use of local Cassandra then each new agent should use it as well.
The main reason for this is the difference in architecture between the local and clustered DB types. When a clustered DB is used, certain info from elements/services/… can be retrieved directly from the DB even by agents which are not hosting that component and the software is designed to assume that each agent is connected to the same clustered DB in this scenario.

We do provide live migration paths to easily transition a cluster to a new type of database configuration. So in your scenario it’d be possible to migrate the entire cluster to Storage as a Service at once.

With Kind Regards,
