Estimate the sensitive cutover window for a WordPress migration based on site type, migration method, DNS TTL and live database activity.
Enter your values and calculate.
This is a planning estimate based on the values you enter. Real WordPress environments can be affected by disk speed, database size, cache behavior, provider limits, plugin architecture, active traffic and third-party services. Verify the production environment before making a live change.
A site can remain available while DNS changes are still propagating. The higher risk is split traffic or new data being written to the old environment after the final database copy.
Use the calculator as a planning aid, then validate the result against the actual WordPress installation, hosting account and production traffic. These notes explain the technical assumptions behind the result and the checks I would make before acting on it.
A site can take hours to copy while remaining online on the source server. Downtime is the period when users cannot reliably use the application. A staged migration is designed to keep that period small or eliminate it for read-only sites.
Orders, form submissions, comments, bookings and membership changes can happen while the final database is being synchronized. The cutover plan must define how those writes are preserved.
After a DNS change, recursive resolvers may continue using the old answer until its TTL expires. Lowering TTL in advance reduces this overlap but does not make all caches update instantly.
A professional cutover has an explicit rollback point. The source is kept intact until the destination has passed functional checks and traffic is confirmed on the new environment.
No. It is an estimate based on the inputs available in a browser. Production WordPress sites can have custom code, unusual server limits, third-party integrations and traffic patterns that change the real requirement.
The calculator runs in your browser. The page does not need an account or a database to calculate the result. Avoid pasting passwords, API keys or private customer information into any planning field.
Use a manual review when the site generates revenue, has active users, contains a large database, uses memberships or subscriptions, has custom integrations, or cannot tolerate an extended rollback window.
The useful part of a planning tool is not the number by itself. It is understanding which assumptions produced the result, which production conditions can change it, and what should be checked before you act. Use this tool as part of a wider migration or infrastructure review rather than as an automatic go/no-go decision.
Migration calculators cannot see the source host, file count, database locks, active writes, plugin behavior or provider throttling. Use the output to decide what needs verification, not as a promise of exact downtime.
A WordPress site can take hours to copy while the production cutover lasts only minutes if staging and final synchronization are planned correctly. The safer workflow is to prepare the destination first and keep the final production change as small as practical.
Orders, leads, memberships, bookings, comments and scheduled jobs can change after the first copy. Any tool used for migration planning should be interpreted together with the site’s live write activity and the method used for the final database state.
No. It estimates or organizes specific migration variables. Actual downtime depends on the migration method, live changes, hosting behavior and DNS strategy.
Yes whenever the project permits it. A private destination test exposes compatibility, PHP, database, cache and routing issues before production traffic moves.
Check key URLs, forms, login, checkout if applicable, redirects, SSL, email, cron jobs, cache/CDN behavior and server logs.
