Istio Upgrades

This hands-on lab teaches you how to safely upgrade Istio in production environments using canary upgrades.

You'll learn to:

• Install a specific Istio version using revision labels
• Perform a canary upgrade by installing a new revision alongside the old one
• Migrate workloads from old to new revision using namespace labels
• Verify workload migration and proxy synchronization
• Rollback to previous revision if issues are detected
• Remove old revisions after successful migration

Canary upgrades are the recommended approach for production Istio installations as they allow gradual migration with easy rollback.
