Upgrading Your Service Mesh to Linkerd 2
summary
Describes upgrading a real deployment from Linkerd 1 to Linkerd 2 by deploying a control plane, switching from per-node DaemonSets to per-pod sidecars, and using admission webhooks to inject proxies automatically. Migration runs both meshes concurrently, flips namespaces to new injection, performs rolling redeploys service by service with mutual TLS activating only after peers migrate, and keeps a rollback path. Migration takes hours, is automated from repo pipelines, and completes with no downtime—users don’t notice.
