What R3load mode is used during an inplace SUM database migration option procedure?

The R3load mode referred to in the context of an inplace SUM (Software Update Manager) database migration option is Pipe mode. This mode is designed to facilitate a direct transfer of data from the source database to the target database without writing the data to an intermediate file. This results in a more efficient migration process, as the data is streamed continuously during the migration rather than being dumped and loaded in separate steps.

Using Pipe mode optimizes the overall migration time and reduces the workload on disk space. During the inplace SUM migration, this approach allows for a seamless transition, enabling the process to occur with minimal disruption and ensuring that the cutover to the new database environment is handled efficiently.

Other modes, such as Dump, involve writing the database data to files before loading it into the target, which can take significantly more time and require additional storage. Stream mode typically refers to continuous data processing rather than specific to R3load, and Clone mode is related to creating exact copies rather than handling migrations. Therefore, Pipe mode stands out as the most effective choice in this scenario.
