Server and Service Migration Plan 9/7/25

Dear Gnoppix Users,

I’m performing a major upgrade of our entire server infrastructure. This is a comprehensive migration where all Gnoppix servers and services, including critical services like email, will be moved. I’m anticipate some service interruptions during this process.

Date: Monday, September 8, 2025
Time Window: 12:00 AM to 12:00 PM (12 hours)
Maintenance Type: Major server and service migration.
Expected Impact: Interruption to services is expected.

  1. Objectives

    Migrate all servers and services to the new infrastructure.

    Ensure all critical data is transferred accurately.

    Validate the functionality of all services on the new platform.

    Minimize the duration of service interruption for users.

  2. Team and Responsibilities

    Project Lead: amu

     Oversees the entire migration process.
    
     Manages communication and updates.
    

    Infrastructure Team: [amu]

     Responsible for server setup, data transfer, and configuration.
    
     Manages network and security settings on the new infrastructure.
    

    Application Team: [amu]

     Responsible for deploying and configuring all applications on the new servers.
    
     Performs functional testing and validation of services.
    

    Support Team: [susan]

     Handles all user-reported issues during and after the migration.
    
     Communicates with users regarding the maintenance and any issues.
    
  3. Timeline (UTC+0)

    12:00 AM - 01:00 AM: Pre-Migration Checks

     Finalize all backups of current servers.
    
     Announce the start of maintenance to all stakeholders and users.
    
     Disable public access to all services.
    

    01:00 AM - 08:00 AM: Data and Server Migration

     Begin data transfer from old servers to new ones.
    
     Configure new servers and services.
    
     This is the period with the highest risk of interruption.
    

    08:00 AM - 10:00 AM: Service Deployment and Initial Testing

     Deploy all applications to the new infrastructure.
    
     Perform a series of smoke tests to ensure basic functionality.
    

    10:00 AM - 11:30 AM: In-depth Validation

     Conduct comprehensive testing of all services.
    
     Verify data integrity and application functionality.
    
     Perform load tests to ensure the new infrastructure can handle traffic.
    

    11:30 AM - 12:00 PM: Go/No-Go Decision and Post-Migration Cleanup

     Confirm all systems are operational.
    
     Roll back to the old environment if critical issues are found.
    
     Announce the completion of maintenance and re-enable public access.
    
  4. Communication Plan

    Before Migration (Monday 12:00 AM): Send a final notification to all users and stakeholders.

    During Migration: Provide regular updates (e.g., every 2 hours) on the progress via a designated communication channel.

    After Migration (Monday 12:00 PM): Send a final notification confirming that services are fully operational.

  5. Rollback Plan

    If any critical issues are identified that cannot be resolved within the maintenance window, the team will execute the rollback plan.

    The rollback involves switching all traffic back to the old servers and services.

    The old infrastructure will remain on standby until the new one is fully validated.

Specific tasks may need to be adjusted based on the complexity of the services being migrated.

  • completed - let me know if you find something, Gnoppix and its services are meanwhile really huge. Thanks for understanding.
