Site migration
A Site migration is a controlled transition of a website's public URLs, domain, protocol, hosting infrastructure or platform from one operational state to another.
What it means
A hosting move can preserve visible URLs, while a domain, protocol or route change needs an old-to-new URL mapping and redirects. The workflow therefore separates migration type, parity testing, DNS or application cutover, canonical and sitemap updates, traffic Monitoring and retirement of the old system.
Why it matters
A versioned transition plan protects users and crawlers from missing pages, irrelevant bulk redirects, accidental Noindex rules, partial content transfer and premature shutdown of the previous environment.
Example
A store moves from HTTP to HTTPS and changes product paths only after Crawling the old inventory, testing one-to-one targets, staging self-canonicals, scheduling redirects, Monitoring both hosts and retaining a rollback window.
Common mistakes
Do not combine unrelated redesigns without isolation, redirect every URL to the homepage, omit low-traffic but linked assets, close old hosting immediately, leave staging blocks live or promise rankings will remain unchanged.
How AYSA handles this
Signals reviewed
migration type, old inventory, new mapping, status, content parity, canonical, sitemap, traffic observation
Problem AYSA can identify
AYSA can identify unmapped URLs, irrelevant destinations, parity gaps, redirect chains, retained staging directives and conflicting post-cutover signals.
Recommendation prepared
AYSA prepares a phased migration manifest with owners, exact mappings, validation gates, deployment order, monitoring thresholds and rollback.
Approval preview
The user sees the complete affected inventory, proposed target for each item, parity evidence, dependencies, known unknowns and recovery actions.
Execution
AYSA can apply approved redirects and owned-site signal changes on supported systems; DNS, hosting and external platform actions require the corresponding authority.
Verification
AYSA crawls old and new states, validates mappings and parity, checks Search-facing signals and records traffic or coverage observations without claiming instant processing.
Limits
The evidence remains URL-, application-, crawler-, platform- and time-bound; recommendations, generated drafts, approvals, crawls and monitoring do not automatically certify AI Act or legal compliance, and applicable Article 50 transparency duties require a separate role-and-use assessment from 2 August 2026.

Quick answers
Frequently asked questions
Does every Site migration change URLs?
No. A hosting or CDN move can preserve public URLs, while domain and route changes require explicit mappings.
Will Search performance remain unchanged immediately?
No guarantee is possible. Search systems need time to crawl and process changes, so monitoring and rollback readiness matter.
