My work process

01 - Assessment and Planning

Identify the need for migration (e.g., outdated hardware, scalability requirements). Assess current server environment, including hardware, software, and configurations.

02 - Backup Plan

Perform a full backup of all data and configurations on the existing server. Verify the integrity of the backup to ensure all critical data is captured accurately.

03 - Setup New Environment

Install necessary operating system, software, and applications. Configure network settings, security measures, and access controls.

04 - Data Migration

Transfer data from the old server to the new server using appropriate methods (e.g., rsync, FTP, database dumps).

05 - Testing phase

Test applications, services, and configurations to identify any issues or compatibility issues. Perform performance testing to ensure the new server meets performance requirements.

06 - Final Data Sync and Cutover

Perform a final data sync or delta migration to ensure any changes made on the old server during the migration process are reflected on the new server.

07 - Post-Migration Validation

Verify that all services and applications are functioning as expected on the new server. Test accessibility and functionality from different client environments.

08 - Monitoring and Optimization

Set up monitoring tools to track server performance and stability post-migration. Optimize configurations and settings based on monitoring data to ensure optimal performance.

09 - Documentation

Document the migration process, including any challenges encountered and solutions implemented.

10 - Post-Migration Review

Conduct a post-migration review to evaluate the success of the migration process against the initial goals and requirements.
