Site or e-shop migrations fail when DNS flips without a plan, files/DB are out of sync and there is no rollback. You need staging, lowered TTL ahead of time and a clear cutover window.
Bytesoft runs migrations with a checklist: backups, tests on the new stack, SSL, email/DNS side effects and post-switch monitoring — without promising zero downtime when third parties control DNS.
Lower TTL early, clone to staging, verify CMS/payments/integrations and agree who changes DNS records.
Monitor for 24–72 hours, keep the old environment on standby for rollback and confirm backups on the new stack.
