## What you need to know

### What is an ecommerce migration cutover?

Migration cutover is the controlled switch from the old production store to the new one. It includes final synchronization, validation, authority changes, communications, and the launch decision.

### How should migration cutover be planned?

Create a minute-by-minute runbook with owners, dependencies, freeze points, final data loads, acceptance gates, communications and rollback decisions. Rehearse it before the launch window.

### Should the old store be frozen during cutover?

Freeze affected writes when practical or capture every change reliably during final synchronization. The method must prevent untracked orders, customers, inventory, and financial events.

### How should orders placed during migration be handled?

Route orders to one clearly defined system of record or capture them for the final delta. Never allow both stores to accept orders without a tested method to identify and reconcile them.

### How should inventory changes during migration be handled?

Freeze manual adjustments or record every sale, receipt, transfer and reservation after the inventory snapshot. Apply the final delta before opening the new store for unrestricted selling.

### When should the new store become the system of record?

The new store becomes authoritative only after final synchronization, critical acceptance checks, and formal cutover approval at the documented decision point.

### Who should approve the final launch?

The accountable business launch owner should approve after technical, operational, financial and customer-service owners provide their required evidence. The decision and unresolved exceptions should be recorded.

### A quick store check

Walk through every runbook step with its owner and evidence before the launch window; resolve missing dependencies or ambiguous decisions.

## Frequently asked questions

### Can cutover be managed through chat messages alone?

No. Use a controlled runbook and decision log so steps, owners and approvals are not lost.

### Who can call a pause?

Define that authority in advance for any owner responsible for a critical customer, financial, data or security control.
