Website Migration Cost — 2026 Platform-by-Platform Table

Florin Florea···Based on 600+ project quotes and public rate benchmarks

Quick Answer

A website migration costs $500–$5,000 for a simple platform move and $5,000–$40,000+ when SEO preservation and integrations are done properly. SEO preservation alone runs $5,200–$40,800 on large sites and is the line item cheap quotes skip. The cheapest real move is a same-platform host swap at $300–$1,500; the most expensive is a legacy custom stack to Next.js at $20,000–$120,000+, calibrated against 600+ project quotes and public rate benchmarks.

At the cheap end, a same-platform host swap is $300–$1,500 and a host-to-host move of open-source WordPress is $500–$2,500 — the WordPress migration cost guide covers those paths in detail. The full any-to-any breakdown, including monolithic-to-headless at $25,000–$200,000+, is in the website migration cost deep-dive.

Inside Three of Those Projects

The table rows are averages; the project files show where the money actually went — and which line items you should force into any migration quote before signing.

From our project files

Cosmetics brand — Wix → Shopify

80 SKUs · $8,500 · 6 weeks

What drove the cost

  • Wix's weak ecommerce export meant manual re-entry for most of the catalog
  • Klaviyo and ReCharge had to be re-wired on Shopify — integration re-wiring runs $500–$4,000 per tool
  • Theme adaptation to Shopify Dawn on top of the data move

What to demand in the quote

  • A per-SKU price for product migration — $15–$60/SKU is the honest band
  • Each integration re-wire as its own line item, not "included"
  • A customer password-reset plan: accounts never port cleanly, and the reset campaign costs $600–$3,000

From our project files

Industrial supplier — Magento 2 → Shopify Plus

2,800 SKUs · $48,000 · 22 weeks

What drove the cost

  • Magento's data model rarely maps cleanly to Shopify — customer accounts and B2B pricing tiers needed refactoring
  • 2,800 SKUs of data mapping, variants, and SEO fields at $15–$60 per SKU
  • Search and inventory rebuilt on Stocky + Searchspring

What to demand in the quote

  • A URL redirect map priced per URL ($0.50–$2.00 each) — at this catalog size, SEO preservation alone is a $4,700–$19,900 block
  • Custom integration rebuilds (ERP, WMS, POS) quoted separately at $2,000–$15,000 each
  • 90 days of post-launch monitoring in writing ($1,500–$8,000), not a verbal promise

From our project files

University department — Drupal 7 → WordPress

600 pages · $22,000 · 14 weeks

What drove the cost

  • Drupal's content model maps awkwardly to WordPress custom post types — module-by-module replacement is the slow part
  • 600 pages of template adaptation and content cleanup at $20–$120 per page
  • ACF field modelling to replace the Drupal field structures

What to demand in the quote

  • A pre-migration crawl and full URL inventory before signing ($300–$2,000)
  • The internal link rebuild as a named line item ($800–$6,000) — skipping it leaves redirect chains Google de-prioritizes
  • Structured data re-implementation ($500–$3,000): schema never auto-ports between platforms

SEO Preservation: The $5,200–$40,800 Line Item

The #1 reason migrations cost more than expected. Done badly, you lose 20–60% of organic traffic and never get it back. Done right, you keep 85–95% within 60 days. The checklist below tracks Google’s own site-move documentation — URL mapping, permanent 301 redirects, sitemap resubmission, Search Console monitoring — priced as line items:

Pre-migration crawl + URL inventory$300–$2,000
URL mapping spreadsheet (every old URL → new URL)$500–$8,000
301 redirect implementation$400–$5,000
Hreflang preservation (multilingual sites)$1,000–$8,000
Structured data re-implementation$500–$3,000
XML sitemap + Search Console setup$200–$800
Internal link rebuild$800–$6,000
Post-launch monitoring + fixing (90 days)$1,500–$8,000
Total SEO preservation, on top of the base migration$5,200–$40,800

Most cheap quotes include $500–$2,000 of this work, which is why they fail. In our migration data, sites with full preservation average a 12% traffic dip in week 1–2 and recover by week 6–10; sites without it average a 38% dip and recover only 65–80% within 6 months.

Hidden Migration Costs You Will Hit

From auditing migrations that went over budget, these are the consistent surprises. The top of the subscription-overlap band is simply Shopify’s published Plus plan pricing running alongside the old platform while you switch:

Customer password resets (encryption schemes differ between platforms)$600–$3,000
App / plugin re-purchase on the new platform$200–$5,000
Custom integration rebuilds (ERP, WMS, POS) — per integration$2,000–$15,000
Email deliverability re-warming$500–$2,500
Tracking + analytics rebuild (GA4, pixels, GTM)$800–$4,000
Old + new platform subscription overlap (1–3 months)$30–$2,300/mo

When Is a Migration Worth the Money?

Four reasons that actually justify the spend, from the migration projects we scope:

Maintenance burden

A one-time migration to Shopify or Webflow costs roughly 18 months of the maintenance retainer it eliminates. Past that point the math favors moving.

Page speed is killing conversions

One WordPress site we scoped had 4.8-second mobile LCP; after moving to Next.js it hit 0.9 seconds and conversions rose 31%. Red Core Web Vitals are a math problem, not a taste problem.

The original developer is gone

When every new developer quotes $8,000 to rebuild an unreadable custom theme, migrating to a supported platform costs about the same and removes the risk.

Ecommerce outgrew the platform

WooCommerce works fine to roughly 500 SKUs and $300K/year revenue. Past that, plugin, hosting, and developer hours often exceed what Shopify Plus would cost.

Two rules that cut cost either way: do not redesign during the migration (splitting it into Phase 2 saves 30–50% and isolates risk), and if you run ecommerce, migrate in Q1 — never Q4.

Frequently Asked Questions

How much does it cost to migrate a website?

A website migration costs $500–$5,000 for a simple platform move and $5,000–$40,000+ when SEO preservation and integrations are done properly. Simple CMS swaps (Wix to Squarespace) run $800–$3,500, ecommerce moves like WooCommerce to Shopify run $4,000–$18,000, and enterprise re-platforms like Magento to Shopify Plus run $15,000–$80,000. According to projectcostestimator.com, migrations cost 2–4x more than owners expect because redirects, SEO preservation, and data integrity each eat 30–40% of the budget.

Why are migration quotes so different?

Migration quotes differ because of scope assumptions on SEO preservation, integrations, and historical data. One quote includes URL redirect mapping, integration re-wiring, and post-launch monitoring; another quotes only the platform swap. SEO preservation alone is $5,200–$40,800 depending on site size — always compare total scope, not the headline number.

Will I lose SEO rankings during a migration?

With full SEO preservation (URL mapping, 301 redirects, structured data, hreflang), migrated sites typically see a 12% traffic dip in week 1–2 that recovers by week 6–10. Without proper preservation, the average is a 38% traffic dip with only 65–80% recovery within 6 months. The worst case in the migrations we’ve scoped was 71% permanent traffic loss on a site moved with no redirect work.

How long does a website migration take?

Simple CMS swaps take 3–5 weeks realistically. Ecommerce migrations under 200 SKUs take 6–10 weeks, mid-size ecommerce (500–2,000 SKUs) takes 12–20 weeks, and enterprise re-platforms take 26–52 weeks. Add 4–12 weeks of post-launch SEO stabilization. Migration timelines are routinely underestimated by 40–80%.

What is the cheapest way to migrate a website?

The cheapest paths: a same-host WordPress move runs $300–$800 and a host-to-host move $500–$2,500. Automated tools like Cart2Cart, Matrixify, and LitExtension handle 70–90% of common ecommerce migrations for $100–$1,500 plus developer cleanup. The biggest saver is not redesigning during the migration — migrate first, redesign in Phase 2, and the migration project costs 30–50% less.

How much does it cost to migrate from WooCommerce to Shopify?

A WooCommerce to Shopify migration costs $4,000–$18,000 in 2026. A real 320-SKU store in our calibration set came in at $11,400 over 8 weeks. The budget splits across product data mapping ($15–$60 per SKU), integration re-wiring for tools like Klaviyo ($500–$4,000 each), theme setup, and URL redirect mapping. Skipping the 301 redirect work is what causes the 20–40% organic traffic loss cheap quotes never warn you about.

How much does it cost to migrate from Magento to Shopify Plus?

A Magento to Shopify Plus migration costs $15,000–$80,000. An industrial supplier with 2,800 SKUs in our calibration set paid $48,000 over 22 weeks. Enterprise re-platforms are expensive because customer accounts, B2B pricing tiers, and custom ERP/WMS integrations rarely map cleanly, and SEO preservation at this catalog size alone runs $4,700–$19,900. Budget 90 days of post-launch monitoring in writing, not a verbal promise.

Is migrating my website worth the cost?

Migration is worth it when maintenance is bleeding you, page speed is killing conversions, the original developer is gone, or your store outgrew its platform. A one-time move to Shopify or Webflow costs roughly 18 months of the maintenance retainer it eliminates. Two rules cut the bill: do not redesign during the migration (splitting it into Phase 2 saves 30–50%), and for ecommerce, migrate in Q1, never Q4.
