This is a research-based decision resource. It contains no affiliate tracking, paid placement, numerical ranking, or claim of hands-on testing. Product features, prices, rules, and availability can change; verify current primary information before acting.
Compare website migrations by inventory, mapping, validation, cutover, and aftercare. Verify evidence, complete cost, risks, and exit.
Begin with the outcome you need
A migration must preserve content, URLs, search signals, forms, analytics, access, security, and recovery while infrastructure and ownership change. Treat inventory, mapping, and validation as separate claims; then verify ownership of cutover and aftercare.
A website choice also assigns responsibility for hosting, updates, accessibility, security, performance, backups, domains, integrations, and migration. The editing experience is only one part of long-term ownership.

| Decision area | What to verify | Why it matters |
|---|---|---|
| Inventory | Require current, plan-specific evidence for URLs, content, media, metadata, forms, scripts, accounts, DNS, and integrations. | Without this evidence, the decision can misstate inventory and transfer unplanned work, cost, or risk to the buyer. |
| Mapping | Require current, plan-specific evidence for old-to-new URLs, canonical intent, redirects, status codes, internal links, and exclusions. | Without this evidence, the decision can misstate mapping and transfer unplanned work, cost, or risk to the buyer. |
| Validation | Require current, plan-specific evidence for crawl comparison, rendered pages, structured data, forms, search, analytics, and accessibility. | Without this evidence, the decision can misstate validation and transfer unplanned work, cost, or risk to the buyer. |
| Cutover | Require current, plan-specific evidence for backup, freeze, DNS timing, certificates, rollback trigger, owners, and communication. | Without this evidence, the decision can misstate cutover and transfer unplanned work, cost, or risk to the buyer. |
| Aftercare | Require current, plan-specific evidence for logs, crawl errors, traffic patterns, conversions, redirects, indexation, and legacy retirement. | Without this evidence, the decision can misstate aftercare and transfer unplanned work, cost, or risk to the buyer. |
Who should consider it—and who should pause
The decision is ready to advance when
- Inventory is tied to a defined outcome and the team can document URLs, content, media, metadata, forms, scripts, accounts, DNS, and integrations.
- A representative scenario can demonstrate old-to-new URLs, canonical intent, redirects, status codes, internal links, and exclusions under the buyer’s actual constraints.
- Named owners have the authority and resources to manage backup, freeze, DNS timing, certificates, rollback trigger, owners, and communication, logs, crawl errors, traffic patterns, conversions, redirects, indexation, and legacy retirement, maintenance, recovery, and an eventual exit.
The shortlist needs more work when
- Inventory remains a headline claim rather than evidence covering URLs, content, media, metadata, forms, scripts, accounts, DNS, and integrations.
- The recommendation assumes crawl comparison, rendered pages, structured data, forms, search, analytics, and accessibility will work without confirming prerequisites, exceptions, or responsible parties.
- No written plan assigns ownership for backup, freeze, DNS timing, certificates, rollback trigger, owners, and communication, logs, crawl errors, traffic patterns, conversions, redirects, indexation, and legacy retirement, failure recovery, or replacement.
Move from assumptions to evidence
Build a representative page and workflow in staging, then test accessibility, performance, forms, permissions, backup, update, rollback, export, redirects, and domain control before committing.
- Document the current baseline and required result for Inventory, including URLs, content, media, metadata, forms, scripts, accounts, DNS, and integrations.
- Ask every serious option to demonstrate old-to-new URLs, canonical intent, redirects, status codes, internal links, and exclusions with the same representative scenario and acceptance rule.
- Map prerequisites, inputs, dependencies, and responsible parties for crawl comparison, rendered pages, structured data, forms, search, analytics, and accessibility before comparing price or convenience.
- Simulate a realistic exception involving backup, freeze, DNS timing, certificates, rollback trigger, owners, and communication; record detection, decision authority, communication, recovery, and evidence retained.
- Model the complete first-year, renewal, maintenance, and failure cost associated with logs, crawl errors, traffic patterns, conversions, redirects, indexation, and legacy retirement, including staff and outside-provider time.
- Write a go/no-go record that identifies unresolved assumptions, the person accepting each residual risk, and the tested cancellation, transfer, or replacement path.
Cost, commitments, and exit
Compare the complete commitment, including inventory, mapping, validation, cutover, aftercare, migration and exit. Record renewal, usage, outside-provider, implementation, maintenance, and exit assumptions separately from the advertised starting price.
A web capability is decision-ready only when it works with representative content, assistive interaction, required integrations, production constraints, rollback, and export.
Mistakes that create avoidable cost
- Inventory is reduced to a marketing label instead of checking URLs, content, media, metadata, forms, scripts, accounts, DNS, and integrations.
- Mapping is inferred from a polished demonstration rather than tested against old-to-new URLs, canonical intent, redirects, status codes, internal links, and exclusions.
- Validation moves forward without confirming crawl comparison, rendered pages, structured data, forms, search, analytics, and accessibility and the dependencies behind it.
- Cutover has no accountable owner for backup, freeze, DNS timing, certificates, rollback trigger, owners, and communication.
- Aftercare and the exit decision are deferred until after commitment, even though they depend on logs, crawl errors, traffic patterns, conversions, redirects, indexation, and legacy retirement.
Questions to answer before committing
- For Inventory, what current evidence covers URLs, content, media, metadata, forms, scripts, accounts, DNS, and integrations?
- For Mapping, what current evidence covers old-to-new URLs, canonical intent, redirects, status codes, internal links, and exclusions?
- For Validation, what current evidence covers crawl comparison, rendered pages, structured data, forms, search, analytics, and accessibility?
- For Cutover, what current evidence covers backup, freeze, DNS timing, certificates, rollback trigger, owners, and communication?
- For Aftercare, what current evidence covers logs, crawl errors, traffic patterns, conversions, redirects, indexation, and legacy retirement?
- Which unverified assumption could change the recommendation, who must resolve it, and what is the deadline before commitment?

Bottom line
Choose only when the evidence fits the real use case, responsibilities are assigned, complete cost is understood, and a tested recovery or exit path exists.
How we evaluated this page
We evaluated the decision using current public guidance from W3C Web Accessibility Initiative, WordPress.org Documentation, FTC: Hiring a Web Host and category-specific criteria for scope, evidence, implementation, ongoing responsibility, risk, and exit.
