When to configure manual Data Guard

In scenarios such as migrating databases between ExaDB-D and ExaDB-C@C systems (for example, from ExaDB-D to ExaDB-C@C or vice versa), the utility does not support enabling Data Guard between the source and target databases. This limitation arises because the migration occurs across different service types. Consequently, the utility also does not support switchover or failover operations in these cases.

In such situations, customers must manually enable Data Guard using one of the following methods:

• Manual method: Copy the source database to the target using the dbaascli database duplicate command, and then enable Data Guard using the Data Guard Broker.
• Automated method: Use Zero Downtime Migration (ZDM) to enable Data Guard.
