Website Migration Audit: What to Check Before a Redesign Goes Live

A website redesign can improve the way a brand looks, performs, and converts. It can also create serious problems if the migration is not checked properly before launch.

That is why a website migration audit should never be treated as a last-minute technical task. It is the step that confirms whether the new site is actually ready to replace the old one without losing traffic, leads, or search visibility.

For enterprise sites, the risk is even higher. Large websites usually have more URLs, more templates, more forms, more stakeholders, and more SEO history to protect. A small mistake in redirects, metadata, canonicals, or indexability can affect hundreds or thousands of pages.

This checklist explains what should be reviewed before a redesign goes live so the launch is smoother, safer, and easier to recover if anything goes wrong.

Why a migration audit matters

When a redesign is published, the old site does not just disappear. Search engines still know the old URLs. Users still have bookmarks. Referring sites still send traffic to the existing pages. If the new setup is not ready, those signals can break.

A good migration audit reduces that risk by checking the technical and content elements that support continuity:

• the correct pages are live
• important URLs redirect properly
• metadata is carried over or updated intentionally
• canonical tags point to the right pages
• images and assets load correctly
• tracking and forms still work
• important pages remain indexable

In other words, the audit is about making sure the redesign can launch without damaging the work that already exists.

What to check before the redesign goes live

1. URL structure and redirects

The first thing to check is whether old URLs will resolve cleanly after launch.

Every important old page should have a clear destination. If a page has moved, it should use a proper 301 redirect. If a page still exists, it should return the correct 200 status. Avoid redirect chains, loops, and homepage redirects that hide the real replacement page.

This matters because weak redirects can create crawl waste, ranking loss, and a poor user experience.

2. Canonical tags

Each page should have a canonical URL that matches the intended live version.

If the redesign accidentally points canonicals to staging URLs, old page versions, or unrelated pages, search engines may ignore the new content or treat the page as duplicated.

Canonical checks are especially important when templates were rebuilt, content was migrated, or parameters changed during the redesign.

3. Metadata

Check title tags and meta descriptions page by page, especially for:

• top service pages
• blog posts with traffic
• landing pages with lead potential
• pages that had strong rankings before the redesign

The goal is not just to copy old metadata blindly. The goal is to make sure the most important pages still have meaningful, unique metadata after launch.

If metadata is missing, duplicated, or overwritten by a bad template rule, search performance can drop quickly.

4. Indexability

Make sure the important pages are actually indexable.

That means checking:

• noindex tags
• robots rules
• page status
• sitemap inclusion
• staging blocks that were left behind

It is common for pages to look fine in the browser while still being blocked from indexing. That is a launch risk, not a minor detail.

5. Images and media

The redesign should be checked for broken images, missing featured images, wrong file paths, oversized files, and alt text issues.

If the site relies on visual sections, a missing image can make the entire page look unfinished. If the image is important to the post or landing page, its absence can also weaken engagement.

For enterprise sites, image delivery should be checked on desktop and mobile, not only in the editor.

6. Forms and lead flow

A redesign is not successful if it looks good but breaks the path to inquiry.

Test:

• contact forms
• quote forms
• CTA buttons
• phone links
• WhatsApp links
• thank-you pages
• routing or notification logic

If lead capture is broken, the business may lose conversions even if traffic stays stable.

7. Analytics and tracking

Verify that analytics, tag managers, and conversion events still work after the redesign.

If the site does not record sessions, form submissions, or CTA clicks correctly, you will not know whether the redesign improved performance.

That makes post-launch optimization much harder.

8. Page load and mobile behavior

Check performance on real devices and real networks.

The redesign should not be much slower than the old site, and it should still behave properly on mobile. Watch for layout shifts, slow hero sections, broken menus, and content that moves around during load.

9. Structured data and technical markup

If the old site used schema, review whether the redesign still outputs the right markup.

This includes:

• Article schema
• Organization schema
• Breadcrumb schema
• FAQ schema
• service or local business markup where relevant

A redesign can accidentally remove schema even when the visible page looks correct.

10. Content parity

If the redesign is replacing old pages, make sure the most important content has a proper home in the new structure.

Sometimes content gets lost during a redesign because one page template is cleaner than the old one but no longer contains enough detail to support rankings or conversions.

This is why the audit should compare old and new content carefully before launch.

A practical go-live checklist

Before the redesign goes live, confirm:

• critical URLs redirect correctly
• canonicals are correct
• metadata is present and unique
• robots rules are not blocking important pages
• images load correctly
• forms submit successfully
• analytics and event tracking work
• mobile pages render properly
• schema is present where expected
• the sitemap reflects the live structure

What to do if something is wrong

If the audit finds a problem before launch, fix it before going live whenever possible.

If the issue is small and safe to correct immediately, do that first. If it affects redirects, templates, or CMS rules, document the problem clearly and stop the launch until the fix is verified.

That is usually much cheaper than publishing first and cleaning up later.

Final thought

A redesign is not truly ready until the migration audit says it is.

If the new site is live but redirects are wrong, metadata is missing, canonicals point to the wrong place, or forms do not work, the redesign is unfinished in practice even if it looks complete on the surface.

For enterprise websites, the best launch is the one that protects what already works while improving the parts that need to change.
