## What you need to know

### How do I know whether an ecommerce migration succeeded?

Success means the new store meets approved customer, commercial, operational, data, search, security and financial outcomes without unresolved critical reconciliation gaps.

### What should be checked 24 hours after migration?

Within 24 hours, check availability, errors, checkout, payment/order reconciliation, inventory, integrations, redirects, analytics, and urgent support issues. Confirm the old and new systems are not both performing exclusive actions.

### What should be checked one week after migration?

After one week, review funnel performance, payment and shipping failures, search crawling, data exceptions, support volume and operational workload. Compare matched days and customer segments with the baseline.

### What should be checked one month after migration?

After one month, assess target benefits, conversion, retention signals, search traffic, site performance, operating effort, platform cost and unresolved technical debt. Document follow-up work separately from migration acceptance.

### How should conversion be compared before and after migration?

Compare the same conversion definition across matched periods and segment by device, channel, market, and customer type. Account for tracking changes, promotions, seasonality and traffic mix.

### How should site performance be compared?

Measure the same pages and journeys under comparable devices, locations, traffic, and cache states. Use user-facing metrics and backend latency to locate real changes rather than comparing unrelated averages.

### How should organic traffic be compared?

Compare landing pages, queries, clicks and impressions using matched periods and account for seasonality and brand campaigns. Separate tracking loss from crawling, indexing, and ranking changes.

### How should operational efficiency be compared?

Compare time, error rate and staff effort for representative tasks such as catalog updates, order exceptions and releases. Include new manual work introduced by the platform instead of measuring only faster steps.

### A quick store check

Select one promised benefit and show its baseline, comparable post-launch measure, owner and explanation of confounding changes.

## Frequently asked questions

### Can launch completion prove migration success?

No. Completion shows the move occurred; success requires customer, business and operational outcomes over time.

### Should every metric improve immediately?

No. Account for stabilization, recrawling, seasonality, promotions and measurement changes.
