Managing Infrastructure During Migrations

Migrations are complex operations. A successful migration requires careful planning, robust automated systems, and a clear communication channel between engineering and business stakeholders.

Pre-Migration Checklist

Before starting any migration, ensure you have:

1. Complete inventory of assets to be moved.

2. Verified backups of all databases and file stores.

3. Lowered TTL settings on DNS records for quick fallback if needed.

Execution Stage

During the migration:

• Monitor ingress and egress rates.
• Keep a detailed audit log of commands executed.
• Maintain a clear rollback path if something goes wrong.

Post-Migration Verification

Once migration is complete, run comprehensive health checks and sanity testing to verify data integrity and performance.
