ZTABS provides platform migration services — We migrate websites, applications, and entire platforms from legacy stacks to modern technologies — WordPress to Next.js, monoliths to microservices, on-prem to cloud — with zero data loss and minimal downtime. Our capabilities include WordPress to Next.js migration, legacy app modernization, E-commerce platform migration, and more.
Run 60+ platform migrations (CMS, e-commerce, framework, cloud) — every migration ships with redirect maps tested in staging, full rollback rehearsed pre-cutover, and SEO traffic typically held within 5% in the first 30 days.
Platform migration is high-stakes work. A poorly executed migration destroys years of SEO rankings, breaks user workflows, and loses data. We treat every migration as a preservation project first and a modernization project second — mapping everything that exists before we build anything new.
We handle four core migration paths: WordPress to Next.js (converting PHP sites to blazing-fast React applications with headless CMS), Magento to Shopify (moving complex e-commerce stores to a simpler, cheaper platform), WooCommerce to Shopify (escaping WordPress maintenance for reliable hosted commerce), and legacy app modernization (rebuilding aging PHP,.NET, Java, or Access applications in modern stacks). Every migration type follows the same core principles: complete data audit before we touch anything, parallel environments so nothing breaks during transition, 301 redirect mapping for SEO preservation, automated testing to verify parity between old and new systems, and 60 days of post-launch monitoring. We use AI throughout the process — automated content extraction, intelligent URL pattern matching, and AI-assisted visual comparison testing.
Performance improvements are dramatic: WordPress sites scoring 40–60 on Core Web Vitals consistently score 90+ after migration to Next.js. E-commerce migrations typically reduce operational costs by 40–60% while improving checkout conversion rates.
Each migration type has unique requirements. Explore our dedicated service pages for detailed process, pricing, and FAQ information.
We migrate WordPress sites to Next.js — converting PHP templates to React components, moving content to a headless CMS, and delivering 90+ Core Web Vitals scores. Every URL redirected, every ranking preserved, every page faster.

Across our portfolio, we track delivery patterns to improve outcomes. Our internal data from 2023-2026 shows:
| Alternative | Best For | Cost Signal | Biggest Gotcha |
|---|---|---|---|
| Platform-native migration tools (Shopify Transporter, WP All Export, CMS importers) | Simple catalog/content moves where source and destination share compatible schemas. | Often free or $50–$500 one-time (indicative). | Tools handle the 80% easy case but miss URL redirects, metadata, inbound links, and integrations. Ship a migration tool-only project and SEO tanks for 3–6 months. |
| Freelancer (Upwork, Fiverr, TopTal) | Small migrations (<500 posts, <200 SKUs) with no complex integrations. | $30–$120/hour; typical project $2K–$15K (indicative). | No SEO preservation plan, no integration inventory, no go/no-go checklist. Typical failure mode: goes live Friday, traffic drops 40% by Monday, no one knows why. |
| Boutique migration specialist (ZTABS tier) | Mid-market migrations with 1K–10K items, custom integrations, and an existing SEO footprint to protect. | $120–$200/hour; $30K–$200K per project (indicative). | We insist on a pre-migration audit (URL inventory, backlink map, conversion path report) — adds $5K–$10K but catches SEO landmines. Founders who skip it regret it in month 2. |
| Big digital agencies (VML, Publicis Sapient, Wunderman) | Fortune 500 replatforming with change management, brand redesign, and multi-geo rollouts. | $200–$400/hour; $500K–$10M engagements (indicative). | Project timelines 12–24 months typical; senior talent rotates across accounts. For mid-market, expect 2–3× markup for similar output. |
| Platform's professional services (Shopify Plus Partners, Contentful Solutions) | Migrations where deep platform-specific experience matters (B2B Shopify Plus, headless Contentful). | $150–$300/hour; $50K–$500K engagements (indicative). | Vendor partners optimize for platform success — which correlates with your success but isn't identical. Independent shops will push back when the platform is the wrong answer. |
Migration vs. staying put. A legacy WordPress on a $500/month managed host + 20 hrs/month dev maintenance ($3K) = $42K/year. Migrating to Next.js + headless CMS: $50K project + $200/month hosting + 4 hrs/month dev ($600) = ~$9.6K/year ongoing. Payback on migration cost: ~18 months, but benefits (speed, conversions, SEO) typically lift revenue 10–25% — hard savings alone justify migration past 18 months; revenue upside makes it worthwhile immediately for sites >$500K/year. SEO-aware migration premium. Basic migration: $20K. SEO-preserving migration (URL mapping, 301 plan, schema, internal-link re-audit, canonical/meta-tag carry-over): $35K — 75% premium. For a site earning $2M/year organic traffic, losing 30% SEO for 3 months = $150K revenue hit. SEO premium pays for itself 4× on even a small loss. Below $100K/year organic revenue, basic migration with post-launch fixes is acceptable. Replatform vs. staying on Shopify Plus custom. A Shopify Plus store at $2.3K/month × 12 = $28K + $30K–$80K/year customization. Migrating to custom headless: $120K one-time + $2K/month infra + $50K/year dev. Custom wins TCO in year 4 for high-volume ($10M+ GMV) stores; below $3M GMV, Shopify Plus's platform velocity wins.
A client's migration mapped top 5K URLs but missed 300 long-tail category pages that drove 40% of organic revenue. Traffic dropped 35% in 10 days. Fix: ALWAYS extract URLs from Google Search Console (top-URLs-by-clicks + top-URLs-by-impressions) over the last 12 months, NOT just sitemap. Map every URL with >5 impressions/month.
A Shopify import converted – into – but kept some raw; half the product descriptions showed broken characters. Fix: always validate a 1% sample of imported content against source manually, plus programmatic entity checks. Use Playwright + visual diff (Percy/Chromatic) to compare before/after on 50 random PDPs.
The old site had /blog/post-title; new site used /insights/2024/post-title. High-authority backlinks now 404. Fix: NEVER change URL structure during migration unless necessary; if you must, implement 301s AND email top 50 referring domains to update their links. Use Ahrefs/Semrush to identify top inbound links worth notifying.
WordPress used Elasticsearch; new Next.js site used basic Algolia index missing synonyms + typo tolerance. Internal search conversion dropped 60%. Fix: audit the old search's behavior (query logs, top-no-result queries, synonyms) and replicate on new platform. Compare conversion from search pre/post with A/B test when possible.
GA4 tracking tag was missing on 3 template pages post-migration; client thought 'traffic is down 20%' when it was actually just tracking gap. Fix: use Tag Assistant + a crawler (Screaming Frog with custom extraction) to verify tracking on 100% of templates before cutover. Also compare GA4 vs. server logs for the first 72 hours.
