CMS Migration Services: Move Platforms Without Losing SEO Equity.
Replatforming WordPress to Webflow, Shopify to headless, Contentful to Sanity, or Drupal to anything modern? A botched migration surrenders 40–80% of your organic traffic in the first 60 days. MV3 handles the full move: content parity, URL mapping, 301 redirects, schema, tracking, DNS cutover, and 30-day post-launch monitoring. Rankings, revenue, and conversion tracking survive the switch.
See a sample migration timeline →A CMS migration is the coordinated move of a website from one content management system to another, e.g., WordPress to Webflow, Shopify to headless, Drupal to Sanity. Done correctly, it preserves every URL, redirect, ranking, schema signal, tracking event, and revenue stream. Done incorrectly, it can drop organic traffic 40–80% in the first 60 days. MV3 delivers the full technical migration: content parity, 1:1 URL mapping, 301 redirect chain, schema and tracking re-implementation, DNS cutover, and 30 days of post-launch ranking monitoring, on a fixed project fee.
A Complete Migration. Not Just a Content Export.
A CMS export tool ships you a JSON blob and calls it done. MV3 runs the six workstreams that actually determine whether your rankings, revenue, and tracking survive the replatform.
Every post, page, product, taxonomy, custom field, image, and media asset moved to the target CMS with 1:1 fidelity. Content models rebuilt in the new platform, editorial workflows tested, media re-optimized for the target CDN.
A per-URL mapping spreadsheet built from a full crawl of the source site (Screaming Frog + GSC + Ahrefs), reviewed against the target IA, then deployed as a single 301 redirect chain with no double-hops. Every legacy URL either resolves or explicitly redirects.
Every JSON-LD block, Open Graph tag, breadcrumb schema, Article/Product/FAQPage/Organization markup re-implemented on the target CMS and validated against Google’s Rich Results Test before cutover.
GA4 property, GTM container, Meta Pixel, LinkedIn Insight Tag, Google Ads conversion, Search Console verification, all re-implemented and QA’d before cutover. No conversion tracking gap during launch week.
Full cutover runbook: TTL pre-drop, staging validation, DNS switch, propagation monitoring, SSL cert issuance, CDN warm-up, and forced re-crawl via GSC + IndexNow. Executed inside a 30-minute low-traffic window with rollback ready.
Daily rank tracking (top 500 keywords), GSC coverage error monitoring, crawl-error triage, redirect chain re-validation, and Core Web Vitals watch for 30 days after cutover. Findings resolved as they surface, not batched.
A 6-Phase Migration. Fixed Scope. Fixed Fee.
Timeline shown for a representative 250–1,000 URL B2B SaaS migration. Larger sites and legacy platforms scale the middle phases; the cutover and monitoring windows stay fixed.
Crawl the source. Nothing gets built until every URL is mapped and every redirect target is confirmed.
Development on the target CMS runs in parallel with content migration, the source site stays live and rank-stable throughout.
Cutover only happens after staging QA passes, redirect chain is validated, and rollback is warm. No exceptions.
Three reasons you cannot lose on this migration.
Every CMS migration ships with three written guarantees. If we miss any of them, the outcome is on us.
Your SOW price is locked at signature. Change orders happen only when scope changes, in writing, with your approval. No surprise invoices, no hourly creep.
MV3-managed cutovers target 0% organic traffic loss, measured against a 28-day pre-cutover baseline. Ranking regression beyond variance triggers remediation at no additional cost through week 4 of monitoring.
Source CMS stays hot through the first 30 days post-cutover. If a P0 issue surfaces on the target platform, we roll DNS back inside 60 minutes while remediation runs on staging.
We Plan the Move. Then We Move It.
Migration-as-consulting hands you a Notion doc and lets your engineers guess. Migration-as-agency lands the strategic mistakes at scale. MV3 combines the diagnostic thesis with the engineers who execute it, one team, one accountability line, one fixed fee.
Why migrations lose rankings, and how ours don’t.
Every migration failure MV3 has autopsied traces to one of five root causes. Our discovery phase closes each one before a single line of code is written on the target CMS.
- 1Full crawl-based URL inventory, every legacy URL accounted for, no orphans left behind.
- 2Redirect strategy signed off before build: no 302s, no chains, no protocol mismatches.
- 3Schema + tracking parity mapped per URL type, not just the homepage.
- 4Cutover runbook rehearsed on staging before touching production DNS.
- 5Rollback plan warm from cutover minute one through week four of monitoring.
One team ships the plan, migration, not memo.
The same engineers who scoped the SOW build the target CMS, run the migration scripts, execute the DNS cutover, and monitor rankings post-launch. No hand-offs to a partner shop mid-project.
- 1Target CMS build: content models, templates, editorial workflows, media pipeline.
- 2Scripted content migration in batches, with QA parity checks between source and target.
- 3Schema + tracking redeployed and validated against Rich Results Test + GTM debug + GA4 realtime.
- 4DNS cutover executed inside a 30-min low-traffic window with monitored propagation.
- 530-day post-launch monitoring: rank tracking, GSC coverage, crawl errors, CWV, redirect chain audits.

How We Run Every Migration.
Same protocol every project. Reproducible, documented, rehearsed on staging before it touches production.
Full source crawl (Screaming Frog + GSC + Ahrefs). Content inventory, redirect audit, tracking audit, IA gap map.
1:1 URL mapping spreadsheet, content-model design on target CMS, schema + tracking parity plan, cutover runbook drafted.
Target CMS built, content migrated in scripted batches, media re-optimized, schema and tracking re-implemented in staging.
Full parity validation: crawl comparison, redirect test, schema validation, tracking QA, Core Web Vitals, accessibility, rollback rehearsal.
30-min DNS window, IndexNow + GSC re-crawl trigger, then 30 days of daily rank + GSC + CWV monitoring with real-time triage.
What buyers say 90 days after cutover.
Outcomes reported by CMS migration clients after 90 days of post-launch monitoring. Personas are composite illustrations of role, stage, and category.
We moved from WordPress to Sanity across 1,400 URLs with zero ranking regression. GSC coverage stayed flat, organic sessions ticked up 4% in the first month. Our SEO lead called it the cleanest replatform he had ever seen.
The migration audit surfaced a 302 chain that would have killed 62% of our category traffic. Caught it in staging, fixed it before cutover, and hit our target date without a single P0 escalation.
Shopify to headless commerce is where migrations go to die. MV3 shipped it in 9 weeks, kept every 301 mapped 1:1, and had GA4 plus GTM firing on launch day. Revenue tracking never dropped a single event.

The Cost of a Botched Replatform Is Bigger Than the Migration Itself.
Aggregate patterns MV3’s technical team has observed across B2B SaaS migration audits, trailing 24 months.
organic traffic drop when 301 chains contain double-hops or 302s during cutover
of failed migrations had schema markup missing on the target CMS at launch
of DIY replatforms lose GA4 or GTM event tracking on at least one conversion path
ranking loss target on MV3-managed migrations with 30-day monitoring engaged
Individual results depend on site size, CMS pair, and pre-migration technical health. Ranking-preservation target requires MV3-managed cutover.
Every migration is scoped from your intake. You receive a fixed-fee SOW inside one business day, no overage billing, no surprise change orders.
Typical project range depends on source/target CMS pair, page count, and integration surface.
- Full source crawl + content inventory + redirect audit
- 1:1 URL mapping spreadsheet + 301 redirect deployment
- Content migration with source↔target parity QA
- Schema + JSON-LD + Open Graph re-implementation
- GA4, GTM, Meta Pixel, LinkedIn tag re-implementation
- DNS cutover runbook + 30-min execution window
- 30 days post-launch rank, GSC + CWV monitoring
- Rollback plan warm through week 4 post-cutover

This is not for you if…
We hold a hard fit bar on CMS migrations. If any of the below is true, we’re not the right vendor and we’ll say so on the intro call.
- You want the cheapest bid. Migrations are priced on scope, not on hours. Cheaper freelancers will win on price and cost you 40 to 80 percent of your organic traffic. That trade is not close.
- You need to cut over in under 3 weeks. Rushed migrations skip the staging QA and cutover rehearsal that make ranking preservation possible. If the deadline cannot move, we are not the fit.
- You have not chosen the target CMS yet and want us to pick blind. Our discovery reviews your candidate, but final selection stays with you. If you need us to lead vendor selection independent of migration scope, that is a separate engagement.
- You want to skip the 30-day post-launch monitoring. Monitoring is where the ranking-preservation guarantee lives. Skipping it means we cannot back the SLA and neither can you.
- You are pre-launch or pre-revenue. Migrations preserve equity; you cannot preserve what does not exist yet. Ship v1 on a stable platform first, then hire us when the traffic is worth defending.
