In this lesson, you will learn:

  • What to do on go-live day
  • How to watch the first scan
  • How to handle a surprise

🔁 Quick look back: Last time: Go-Live Readiness Review. You learned how Anita approved go-live.

1 The Problem: Surprises Happen on the First Night

On wave 1 night, you activate SNWR Mumbai Servers Nightly. Even with good tests:

  • Something new can appear.
  • People are tired and it’s late.

🎯 The problem: Surprises happen on the first night.

👉 The fix: Follow a simple go-live plan, watch closely and keep calm.

Timeline of go-live night.
Figure 1. Wave 1 night.

2 The plan

  1. Activate the wave’s schedule through the change.
  2. Watch the status and early failures.
  3. Handle problems with the troubleshooting method.
  4. Send a short summary in the morning.

3 Handling a surprise

Use the four questions. Fix what’s safe to fix. If in doubt, use the emergency stop and fix in daylight.

4 Project Clear View: How We Implemented It

📍 Situation: Wave 1 night: Mumbai servers.

🧭 Decision: Activate, watch and handle whatever comes up.

🛠️ Steps we took:

  1. Activated the schedule at 00:45.
  2. At 01:20, Windows logins failed: svc-snow-disc had been rotated that afternoon.
  3. Priya updated the credential; you retried the failed servers.
  4. Sent Hana the morning summary.

✅ What we verified:

  • The scan completed at 03:10.
  • All Mumbai servers were updated.

📁 Evidence: The morning summary and a note to check rotations before each wave.

5 Quick recap

  • Follow a simple go-live plan.
  • Watch the first scan closely.
  • Use the troubleshooting method under pressure.
  • Send a morning summary.
