Where are the R3load processes located when performing the Database Migration Option (DMO) procedure using in-place migration?

The R3load processes are critical components of the Data Migration Option (DMO) procedure during an in-place migration, primarily because they handle the data extraction and loading processes. When using DMO for in-place migration, the primary application server (PAS) is where the R3load processes are instantiated and executed. This is due to the fact that the PAS is responsible for managing the application layer and its related processes, ensuring that the necessary data is retrieved from the existing system and transferred to the new database environment.

The in-place migration process relies on this architecture, as the R3load utilities need to access the application data directly and efficiently. Since the PAS is directly involved in interacting with the application that hosts the business logic, it is the most suitable location for these processes to run, allowing seamless data migration with minimal disruption.

The other options, such as the Backup Server or Database Host, do not house the R3load processes during this specific migration scenario. The Backup Server’s role is primarily related to securing and storing backups rather than running data migration processes, while the Database Host is typically focused on database management and hosting rather than executing the application layer tasks associated with R3load. The Secondary Application Server would only be engaged as a resource under
