Client Project Production Cutover & Launch Day Pack (With AI)

Freelancers and SMB teams often treat “go-live” as flipping a DNS record at 5 p.m. on a Friday, then refreshing Slack until someone complains. That is how you miss rollback triggers, skip written smoke tests, and leave the client wondering who owns production during the first hour. Production cutover is the controlled window when you move from approved staging to live systems—not UAT test week, not milestone billing sign-off, and not the multi-week hypercare window after launch.

This playbook sits after UAT go/no-go and before hypercare. It pairs ChatGPT for FACT/ASSUMPTION cutover checklists, a Cutover Brief in Google Docs, a smoke-test log in Google Sheets, and a three-email Gmail war-room cadence through T+0 and the first production hour. If you have not run structured acceptance testing yet, start with UAT & go-live testing. For the first month after launch, pivot to hypercare.

When to run a formal cutover pack

Open this pack when all are true:

• UAT (or equivalent) ended with a written go decision and a frozen release candidate build ID.
• Production credentials, DNS, payment keys, or content publishes are scheduled for a specific window.
• Client and vendor stakeholders need a single written source of truth during the flip.
• Rollback is technically possible and the client expects a named decision-maker at T+0.

Skip it if you are still fixing UAT blockers, negotiating scope via change requests, or only shipping internal tools with no client-visible cutover.

End-to-end flow

Step 1 — Cutover checklist from facts only (ChatGPT)

Paste the go/no-go summary, RC build ID, and environment map. Use FACT vs ASSUMPTION labeling so nobody treats a guess as done:

You are a delivery lead writing a one-hour production cutover. Facts: [paste UAT go summary, RC version, URLs, DNS owner, payment keys owner, rollback method].

Rules:
- Mark every line FACT (verified) or ASSUMPTION (must verify before T+0)
- Output: ordered cutover steps with owner, duration estimate, verification per step
- Output: 8–15 production smoke tests runnable in 15 minutes
- Output: rollback triggers (any one = stop and roll back)
- No vanity steps. No "monitor as needed" without a named check.

Format as tables ready for Google Docs.

You approve every ASSUMPTION line before sharing the brief with the client.

Step 2 — One-page Cutover Brief (Google Docs)

Section	Content
Header	Project name, RC build ID, cutover date/time (client local TZ + UTC)
Participants	War-room roles: cutover lead, client approver, DNS/hosting owner, support contact
Pre-flight (T-24h)	Backups verified, maintenance page ready, comms draft approved
Cutover sequence	Numbered steps: who, what, expected signal when done
Smoke tests	Link to Sheets log; pass/fail rule before calling "live"
Rollback plan	Last-good version, DNS TTL note, who presses rollback, max decision time
Out of scope tonight	Deferred items with ticket IDs (not hidden scope creep)
Hypercare bridge	Start date, channels, severity routing into defect backlog

Share view-only to client execs; grant comment to technical owners until T-1 sign-off.

Step 3 — Smoke test log (Google Sheets)

Columns: Test ID, Area, Steps, Expected, Actual, Pass/Fail, Tester, Time (UTC), Evidence link.

Run smoke tests immediately after the last cutover step—not the next morning. Block the "we are live" Gmail until P0 smoke paths are green or explicitly waived in writing by the client approver.

Rollback triggers (examples—customize in the brief): payment capture fails on a test transaction, auth/login broken for admin users, critical API error rate above agreed threshold, DNS still resolving to old IP after TTL window.

Step 4 — Gmail war-room cadence (three emails)

Email 1 (T-24h) — Subject: [Project] Production cutover tomorrow — roles & window

• Cutover window in client local time
• Link to Cutover Brief
• Who joins the call or thread; expected client approver at T+0
• Ask for one-line confirmation: "We accept rollback plan as written"

Email 2 (T-1h or at start) — Subject: [Project] Cutover starting — step-by-step updates

• "We are executing step 1 of N"
• Promise updates at defined milestones (DNS flipped, app deployed, smoke started)
• Single reply-all thread—no parallel Slack DMs for go/no-go

Email 3 (after smoke pass or rollback) — Subject: [Project] Production live or [Project] Rollback complete — next steps

• Smoke summary (counts pass/fail)
• Hypercare start date + how to report defects
• If rollback: factual status, next retry window, no blame language

You send; ChatGPT only drafts. Never automate client production emails without human review.

Step 5 — Execute, decide, document

During the window:

1. One cutover lead speaks on status; others execute.
2. Log actual times in the Brief (audit trail for warranty and hypercare).
3. If a step fails, pause the sequence—do not skip verification to "catch up."
4. At rollback decision point, client approver replies in writing on the email thread.

After green smoke:

• Update the Brief header with "Production live as of [timestamp]."
• Open or refresh the hypercare defect backlog so launch-night fixes are not lost in DMs.
• Schedule a 24h check-in (can reuse weekly status format).

Common mistakes

• Confusing UAT with cutover — UAT proves the build; cutover moves traffic. Different checklists, different owners.
• No written rollback — "We can redeploy" is not a plan. Name version, command, and decision clock.
• Announcing live before smoke — Marketing toggles should wait for technical smoke pass unless client explicitly accepts risk in writing.
• Friday night heroics — Move cutover to a client business window with rollback time left the same day.

What to hand off next

Outcome	Next playbook
Live + stable smoke	Hypercare window
Live + warranty clause	Warranty defect triage
Rollback, retry next week	Revisit UAT scope for failed paths
Ongoing ops support sold	Retainer kickoff

Quick copy: smoke test seed (ChatGPT output)

Use as a starting table in Sheets—trim to your stack:

ID	Area	Steps	Expected
S1	Auth	Log in as admin test user	Dashboard loads, session cookie set
S2	Core flow	Complete one happy-path transaction	Success state + confirmation email
S3	Payments	$0.01 or sandbox charge	Gateway shows captured, order status paid
S4	Content	Load top 3 public URLs	200, no mixed-content warnings
S5	Integrations	Trigger webhook or sync job	Last run timestamp within 5 min
S6	Performance	Run agreed spot check (LCP or API p95)	Below threshold in brief
S7	SEO/redirect	Hit legacy URL if migrating	301 to correct target
S8	Admin	Create and delete test record	CRUD audit entry if required

Bottom line

UAT earns the right to cut over; cutover earns the right to call production live. A one-page Cutover Brief, a Sheets smoke log, and a three-email Gmail cadence keep freelancers and SMB teams honest when the lever moves—so hypercare starts with facts, not folklore.
