How we run migrations across 2,800 microservices

Migrating 2,800 microservices can be daunting, but a centrally driven approach can mitigate risks and maintain consistency. By relying on a core team to handle migrations, leveraging automation, and using consistent technologies such as Go and a monorepo, large-scale updates like transitioning from OpenTracing to OpenTelemetry can be managed smoothly. Planning, transparent communication, and flexible configuration systems are essential to achieve effective, downtime-free migrations.
