No, manually migrating a Sangfor cluster controller function to another node within the HCI environment is not recommended and might not be feasible. Here's why:

    Preserves System Stability: Sangfor HCI is designed for automatic failover mechanisms. The cluster controller functionality is crucial for maintaining overall system stability and ensuring service continuity. Manual intervention disrupts this automated process, potentially leading to unexpected behavior or downtime.

    Synchronized Operations: Cluster controllers operate in an active/passive high-availability mode, constantly synchronizing data to guarantee consistent state across both nodes. Manual migration might disrupt this synchronization, causing data inconsistency and compromising system integrity.

    Potential Data Loss:  Forcing a manual switch without proper failover procedures could lead to data loss or service disruptions. Sangfor HCI's designed failover prioritizes data integrity and minimizes downtime.

Recommended Approach:

In situations where a planned migration is necessary due to hardware failure or maintenance, it's crucial to consult Sangfor support.  Support engineers possess the expertise and tools to perform a safe and controlled migration process while ensuring data integrity and service continuity.

Here are the general steps involved in a supported migration process:

    Initiate Support Ticket: Contact Sangfor support and explain the situation.
    Gather Information: Provide support with necessary details like Sangfor HCI version, node information, and the reason for the migration.
    Guided Migration: Sangfor support will guide you through the recommended procedure, which might involve utilizing specific utilities or tools to ensure a smooth and safe migration.
