Which run level can a PCE migration run at?

In the context of a PCE (Policy Compute Engine) migration, it is essential to understand that run levels refer to the state of a Linux system, where different levels allow for different system functions and services to run. Run level 1 is often referred to as single-user mode. This mode is primarily used for maintenance tasks, allowing for configurations and troubleshooting without the interference of network services or additional users.

During a PCE migration, running in run level 1 provides a controlled environment where the primary focus is on the migration process itself without additional processes or services that could interfere. This minimizes the risk of disruptions and ensures that the migration can occur smoothly, as only the essential system tasks run. This designated environment is particularly crucial for the migration of critical components like the PCE, where stability and controlled conditions are necessary to ensure successful transfer and configuration of policies.

Other run levels, which include multi-user modes and graphical user interfaces, introduce additional complexities, like networked services and multi-user interactions, which are not optimal during a migration scenario. Hence, selecting run level 1 for the migration process is a strategic choice that aligns with the best practices for system maintenance and migration tasks in a Linux environment.
