Near-zero downtime migration with a rehearsal-first playbook
True zero downtime requires rehearsal — not hope. SiteSkite lets you restore and validate the full site on the new host in Sandbox before DNS TTL expires, so cutover windows shrink to minutes.

Why migrations cause downtime
DNS, untested destinations, and long TTLs turn small mistakes into long outages.
First traffic hits an untested server
Without rehearsal, cutover day is the first time the new stack serves real users.
- Long DNS TTL extends perceived downtime.
- No rollback doubles outage when cutover fails.
- Commerce sites lose orders during unplanned windows.
Rehearse twice. Cut over once. Monitor immediately.
The low-downtime playbook
Sandbox dress rehearsal → TTL planning → final backup → DNS switch → BirdEye monitoring.
- Full site rehearsal on destination in Sandbox.
- TTL lowered 48 hours before cutover.
- Fresh backup at migration window.
- Monitoring confirms new host health.
Boring migrations are successful migrations.
Downtime during migration
Every minute offline costs trust, SEO, and revenue.
DNS propagation delays
Long TTLs extend perceived downtime.
Untested destination
First traffic hits an untested server.
No fast rollback
Failed cutover without backup doubles outage length.
Low-downtime cutover
Rehearse fully → lower TTL → restore → DNS → monitor.
Full rehearsal
Restore and QA complete site on new host in Sandbox.
Lower DNS TTL
48h before cutover — reduce propagation wait.
Final sync backup
Fresh restore point at cutover window.
DNS switch & monitor
BirdEye confirms new host serving traffic.
Relevant features
Rehearsal and monitoring beat heroic live sync.
