WordPress Migration Testing — Preview Your Site Before DNS Cutover

Moving WordPress to a new host is risky: broken images, missing plugins, redirect loops, white-screen-of-death after DNS propagates. TestURL.live gives you a free, shareable preview URL on the new server — so you catch every problem before your visitors do.

Why WordPress Migrations Break

A WordPress site is far more than the files in wp-content. Every theme stores image paths in the database as absolute URLs; page builders like Elementor and Divi cache layouts that reference the old hostname; plugins write license keys, callback URLs, and CDN settings that the new server inherits but doesn't know how to validate. When you simply repoint DNS and hope, the failure modes are familiar:

The traditional workaround — editing your local hosts file — only previews the site for you. You can't share it with the client. You can't run Lighthouse against it. You can't run an automated visual-diff between old and new. And the moment you forget to revert that hosts entry, your normal browsing breaks. There is a better way.

How TestURL.live Tests a WordPress Migration

Instead of editing hosts, we give you a temporary subdomain that proxies your domain through the new server's IP — exactly as your visitors will experience the site after DNS propagates.

  1. Enter your WordPress domain (e.g. yoursite.com) and the IP of the new server.
  2. We spin up a private subdomain like xyzab.testurl.live that proxies requests to the new IP, but presents your real domain in the Host header so WordPress responds correctly.
  3. Open the preview URL — you're now browsing your WordPress site as it lives on the new server, before any DNS change.
  4. Run our automated comparison: visual screenshots of old vs new, Lighthouse performance scores, SEO meta checks, security-header audit, and a console-error scan.
  5. Share the preview URL with your client or QA team. When you're satisfied, change DNS with confidence.

What You Can Verify Before DNS Cutover

Theme & Page Builder

Confirm Elementor, Divi, Bricks, or Gutenberg blocks render identically. Pixel-level visual diff flags any layout shift.

Plugins & Functionality

Test forms, search, login, AJAX, REST API, and admin-ajax endpoints. Browser console-error scan surfaces any 500s or missing scripts.

WooCommerce Checkout

Walk through the full cart → checkout → payment flow. Stripe and PayPal sandbox payments work because cookies and sessions persist.

Performance (Lighthouse)

Side-by-side LCP, CLS, TBT, and overall score for old vs new. Catch the case where the new host is slower.

SEO Snapshot

Verify titles, meta descriptions, canonical tags, H1s, and robots.txt didn't get overwritten in the move.

Security Headers

Detect missing HSTS, CSP, X-Frame-Options, or X-Content-Type-Options on the new server.

WordPress Migration Testing — FAQ

How do I test a WordPress site before changing DNS?

Use TestURL.live to generate a temporary preview URL that proxies your domain through the new server's IP. You can browse the WordPress site exactly as your visitors will see it after DNS cutover, without editing your hosts file or changing any DNS records.

Will my WordPress plugins work on the preview URL?

Yes — because the proxy preserves the real Host header, WordPress, the theme, and most plugins behave as if they're on the production domain. Hard-coded URLs are rewritten on the fly so navigation stays inside the preview.

Is this better than editing my hosts file?

Yes. A hosts edit previews the site only on the machine you edited. A TestURL.live preview URL is a sharable link — your client, designer, or QA can open it from anywhere. And forgetting to revert a hosts edit can silently break your other browsing for days.

Does it work with WooCommerce, MemberPress, LearnDash?

Yes. The proxy preserves cookies, sessions, and POST bodies, so cart, checkout, login, membership, and learning-flow tests run end-to-end on the preview.

Can I run Lighthouse on both versions?

Yes — TestURL.live runs Google Lighthouse against your live site and the new-server preview automatically. You'll get a side-by-side performance comparison before flipping DNS.

Is it really free?

The basic preview URL and Lighthouse comparison are free with no signup. The deeper comparison (visual diff, console-error scan, SEO/security audit, downloadable PDF report) is on a paid plan.
