A website migration with clear acceptance criteria.
The new site loads, but old URLs lead nowhere or the form no longer stores enquiries. This guide helps you plan the move and verify more than the appearance of the new website.

Start with the right question
What should you check before a website migration?
Define what changes: the domain, CMS, URL structure, content or several things at once. List important old URLs and record a decision for each. Then choose destination pages and how moved content will be handled.
An HTTP 200 response alone does not prove a successful migration. A URL can show the wrong content, a form can report false success and measurement can stop tracking the same event. Define acceptance criteria, evidence and conditions for stopping or reversing the launch.
Method example
Old URLTarget content
/oferta/uslugi/kontakt/kontakt/stary-poradnik/HTTP 200. But which content?Check the destination, not just the status.

Acceptance and measurement
Check key journeys, enquiry receipt and old URLs. Distinguish a deployment fault from changes in content visibility.
A real excerpt. A practical exercise.
Start with five URLs, not an empty spreadsheet.
The excerpt shows a small migration map. The package contains a completed example and a blank file. Give each URL a decision, then define the test result that will confirm it.
- Choose old URLs important to visitors and the business.
- Assign target content and expected behaviour.
- After launch, retain evidence for every acceptance criterion.

Who it is for and when to use it
Before a CMS, domain or structure change.
For agencies, developers and people reviewing a new website. The guide organises responsibilities and evidence. Backup and cutover procedures still need to match the specific system and infrastructure.
No. The guide organises decisions, URL mapping and release checks. Backup, cutover and recovery details need to match your particular system.
About the publisher: CometWebThat does not automatically preserve the purpose of each piece of content. A migration map requires decisions for individual URLs and suitable successors where they exist.
A backup is a resource. The plan also defines the stopping condition, decision owner, restoration procedure and checks after recovery. Agree these before launch.
