The Zero-Downtime Migration Playbook

Re-platforming shouldn’t mean downtime, lost rankings or a frozen roadmap. This playbook shows how to migrate your DXP with zero disruption.

Why migrations go wrong

Most migration pain is avoidable. It comes from rushing the cutover, underestimating content, and treating SEO as an afterthought. Get ahead of these and the rest is process.

• Big-bang cutovers with no rollback
• Broken redirects that tank search rankings
• Content drift between old and new systems
• No staging environment that mirrors production
• Stakeholders surprised at go-live

The zero-downtime principle

Run old and new in parallel, move traffic gradually, and keep a tested rollback at every stage. Users never see a gap; you never bet the business on a single weekend.

A phased migration plan

1. Audit and freeze scopeInventory every page, asset, integration and redirect. Lock scope before you build.
2. Build in parallelStand up the new platform alongside production with identical content models.
3. Migrate content incrementallyMove section by section with automated validation and a living redirect map.
4. Cut over behind a flagShift a percentage of traffic, watch the metrics, then ramp to 100%.
5. Monitor and hardenTrack errors, Core Web Vitals and rankings for 30 days; keep rollback ready.

Protect content and SEO

• Canonical tags and metadata carried over
• XML sitemap submitted on launch day
• Structured data preserved and re-validated
• Analytics and tag manager verified before cutover
