01
Measure first
Capture current PageSpeed runs, server response, uptime, traffic,
errors, cache behavior, and application versions.
02
Clone and verify
Test the copied site using a temporary host mapping or preview
domain. Verify forms, email, checkout, redirects, cron jobs, and
certificates.
03
Lower DNS risk
Reduce TTL before the move, schedule a quiet window, preserve the
old environment, and document a rollback trigger.
04
Move fresh data
For changing stores or communities, plan a final database sync or
a short maintenance window to prevent lost orders and posts.
05
Watch the launch
Monitor response codes, logs, forms, transactions, DNS, TLS,
search crawling, and real-user errors immediately after cutover.
06
Compare the same pages
Retest representative pages under similar conditions. A migration
is successful when reliability and user outcomes improve—not
merely when one lab score moves.
