Migration Monitoring
Ship Migrations Without the 3 AM Panic
Migrations are high-stakes. One misconfigured redirect, one asset pointing to the old CDN, one page silently serving from the wrong host -- and you are fielding calls at 3 AM. Sitewatch validates redirect chains, detects host drift, and verifies that every linked asset loads correctly on the new infrastructure.
- Redirect chain validation with loop and host drift detection
- Host drift detection through HTTP response analysis
- Asset verification across every migration phase

Why it matters
Migration confidence backed by evidence
Redirect chain validation
Every redirect path is followed and validated: no loops, no excessive hops, correct final destination. Catch misconfigurations before they hit search rankings or strand visitors.
Host drift detection
Sitewatch analyzes HTTP responses to detect when pages are still being served from the old host. Catch split-brain scenarios where some pages moved and others did not.
Asset verification after migration
Verify JS, CSS, and images load correctly on the new host. Catch CDN misconfigurations and missing assets that break functionality after the switch.
Page availability verification
Confirm that pages return valid HTML with correct status codes after migration. Detect NON_HTML_PAGE responses or UNAVAILABLE pages that your visitors would hit.
MIME type verification
Verify that assets on the new host serve the correct content types. Catch CDN misconfigurations that serve HTML error pages instead of your JS or CSS files.
Ongoing post-migration checks
Sitewatch keeps checking daily after cutover. Catch delayed issues that surface once caches expire, DNS propagates fully, or edge cases hit that did not show up on day one.

What Sitewatch catches during migrations
Redirects & routing
- REDIRECT_LOOP -- redirect chains that trap visitors in an infinite loop
- Excessive redirect hops that degrade experience and SEO
- Broken redirect destinations returning error codes
- HOST_DRIFT -- pages redirecting to an unexpected domain or old host
Host & assets
- Host drift detected via HTTP response analysis
- ASSET_MISSING -- scripts, stylesheets, or images failing to load on the new host
- ASSET_MIME_MISMATCH -- assets served with wrong Content-Type after CDN migration
- NON_HTML_PAGE -- pages returning non-HTML responses where HTML is expected
Migration workflow
Monitor every phase of your migration
Baseline before migration
Add your site URLs before the migration. Sitewatch runs checks against the current state -- page responses, linked assets, HTML fingerprints -- so you have a clear baseline to compare against.
Check during and after cutover
As you switch DNS and deploy to the new host, use "Run Check Now" for on-demand checks. Daily automated checks at 6 AM UTC catch anything that slips through.
Get alerted on regressions
When something breaks -- a redirect loop, a missing asset, host drift -- Sitewatch sends alerts across your configured channels with the specific URL, status code, and issue type.
Confirm completion
Once all checks pass consistently, you have evidence that the migration is complete. All pages reachable, all assets loading, no host drift, no redirect issues.
Your next migration, without the panic
Free plan. No credit card. Add your URLs and baseline your site before the migration starts.
Why Sitewatch
Manual migration QA vs Sitewatch
| Feature | Manual QA | Sitewatch |
|---|---|---|
| Redirect validation | Spot-check a few URLs by hand | Every monitored redirect path validated automatically |
| Host verification | Check from one network, hope it is consistent | HTTP-based host drift detection on every check |
| Asset verification | Open pages in a browser and look around | Every linked asset HEAD-requested and MIME-verified |
| Detection timing | Hours to days, usually when a user reports it | Daily automated + on-demand checks |
| Coverage | Key pages only, maybe | All monitored pages and their linked assets |
| Evidence trail | Screenshots pasted in a doc | Typed incidents with URLs, status codes, and fix checklists |

Frequently asked questions
Start at least 48 hours before the migration to establish accurate baselines. Sitewatch will run checks against your current pages, assets, and redirects so any changes after cutover are immediately visible.
Yes. Sitewatch analyzes HTTP responses to detect when pages or assets are still being served from the old host. This helps you confirm that traffic has fully shifted to the new infrastructure.
Sitewatch follows every redirect hop and validates the full chain: no loops, no excessive hops, and a correct final destination. Each redirect path is logged with status codes so you can trace exactly where things go wrong.
Sitewatch uses a 2-of-3 retry confirmation system, so transient issues during cutover are less likely to trigger alerts. You can also time your cutover around the 6 AM UTC daily check and use on-demand checks when you are ready to validate.
Yes. Whether you are migrating from WordPress to a headless CMS, switching hosting providers, or consolidating domains, Sitewatch monitors the same fundamentals: redirects, assets, page availability, and content verification.
