Hiring a Team to Migrate Your WordPress Site: The Decision-Maker's Guide

The Most Important Decision Isn't Technical

You've decided to leave WordPress. The performance data convinced you, the cost analysis checked out, and you're tired of plugin conflicts. Now comes the decision that actually determines whether your migration succeeds or fails: who will do the work?

A great migration team turns 'scary platform change' into 'smooth business upgrade.' A bad one turns it into months of frustration, lost SEO traffic, and broken functionality. The difference isn't just cost — it's whether your business experiences any disruption at all.

Understanding the Three Options

Option 1: Agency

A web development agency assigns a project team: project manager, lead developer, possibly a designer and QA engineer. You get structured processes, regular status meetings, and a guaranteed deliverable.

• Typical cost: $10,000-50,000 depending on site complexity
• Timeline: 4-12 weeks
• Best for: Enterprise sites, complex WooCommerce stores, sites requiring design changes alongside migration
• Strengths: Process maturity, multiple skill sets, accountability, post-launch support contracts
• Weaknesses: Higher cost, longer timelines, potential for over-engineering, communication through PM layer

Look for agencies with specific WordPress migration case studies. General web agencies often underestimate WordPress migration complexity because they don't understand the database structure, plugin data extraction, or SEO implications.

Option 2: Freelance Developer

A single developer handles your migration end-to-end. Communication is direct, timelines are typically shorter, and costs are lower.

• Typical cost: $3,000-10,000
• Timeline: 2-6 weeks
• Best for: Mid-complexity sites (10-50 pages, blog, basic functionality)
• Strengths: Direct communication, faster decision-making, lower overhead costs
• Weaknesses: Single point of failure, quality varies enormously, limited capacity for complex projects

The freelancer market for WordPress migrations is a minefield. For every excellent developer who understands both WordPress internals and modern frameworks, there are ten who'll deliver a mediocre result. Vetting is absolutely critical — more on this below.

Option 3: AI-Assisted Migration Service

A migration specialist uses AI coding tools (Claude, Cursor, GitHub Copilot) to dramatically accelerate the development work. Human expertise drives the strategy, architecture, and quality assurance; AI handles the repetitive coding tasks.

• Typical cost: $500-5,000
• Timeline: 5-15 business days
• Best for: Business sites of any size where the goal is a faithful migration (not a complete redesign)
• Strengths: Fast turnaround, lower cost, AI-generated code is clean and consistent, the result is optimized for ongoing AI editing
• Weaknesses: Newer category with fewer established providers, less suitable for projects requiring significant custom design work

What Makes WordPress Migrations Unique

Not all platform migrations are equal. WordPress migrations have specific challenges that your provider must understand:

Database Complexity

WordPress's database structure — particularly the wp_postmeta table and serialized PHP data from plugins like ACF — requires specialized extraction and transformation. A provider who has only migrated Webflow or Squarespace sites may not understand the challenge of parsing serialized PHP arrays or reconstructing ACF repeater field data.

Plugin Dependency Mapping

Your WordPress site's functionality depends on plugins, and understanding which plugin provides which feature is essential for migration planning. Some features need to be rebuilt in code (contact forms, SEO). Others might be replaced by SaaS services (email marketing, analytics). And some can be dropped entirely (security plugins, caching plugins that are only needed because of WordPress's architecture).

SEO History

WordPress sites that have been live for years have accumulated significant search engine authority. Your provider needs to understand how to preserve this: 301 redirects for every URL that changes, meta tag migration from Yoast/RankMath, sitemap generation, structured data preservation, and Google Search Console monitoring. A botched SEO migration can take 6-12 months to recover from.

Content Volume

WordPress sites tend to have significantly more content than sites on other platforms. A WordPress blog might have 500-2,000+ posts accumulated over years. Each post has meta data, featured images, categories, tags, and internal links. This volume requires automated migration tooling — manual migration is impractical and error-prone at this scale.

Questions to Ask WordPress Migration Teams

These questions are specifically calibrated for WordPress migrations. The quality of the answers tells you everything about the provider's competence:

1. "Walk me through how you extract WordPress content, including ACF custom fields."

Good answer: describes a specific process involving WP-CLI export or REST API, mentions parsing serialized postmeta data, explains how they map ACF field groups to the new CMS schema. Bad answer: 'We'll just export it as XML and import it.' That answer means they've never dealt with complex WordPress data.

2. "How do you handle WordPress media migration?"

Good answer: describes downloading from wp-content/uploads, re-optimizing for modern formats, uploading to new storage, and updating all content references. Mentions responsive image handling and broken image detection. Bad answer: 'We'll copy the uploads folder.' That misses the critical step of updating content references and optimizing images.

3. "What's your SEO migration checklist?"

Good answer: includes redirect mapping for every URL, meta title/description migration from Yoast or RankMath, sitemap generation, Google Search Console submission, crawl error monitoring, structured data preservation, and a post-launch SEO audit. Bad answer: 'We'll set up redirects.' That's one item on a 10-item list.

4. "How do you handle WordPress-specific functionality that relies on plugins?"

Good answer: asks about your specific plugin list, categorizes them (needs code rebuild, can use SaaS replacement, can drop entirely), provides a specific plan for each category. Bad answer: 'We'll rebuild everything in code.' That's not a plan — it's a platitude that ignores the question of scope.

5. "What happens to our search rankings during migration?"

Good answer: acknowledges that a temporary ranking fluctuation is normal (1-3 weeks), explains their redirect strategy, mentions monitoring Google Search Console, and describes their response plan if rankings drop unexpectedly. Bad answer: 'Your rankings won't be affected.' That's either naive or dishonest — all migrations carry some SEO risk.

6. "Can we see a WordPress migration you've completed?"

The single most important question. A provider who has completed WordPress migrations can show you before/after, explain the specific challenges they encountered, and demonstrate that they understand the platform. If they can't show a WordPress-specific example, they're learning on your dime.

Red Flags Specific to WordPress Migration Providers

Watch for these warning signs during the evaluation process:

• They don't ask about your plugin list. Plugins define your WordPress site's functionality. A provider who doesn't audit your plugins doesn't understand the scope of work.
• They quote a fixed price without seeing the site. WordPress migration complexity varies 10x between a simple blog and a WooCommerce store with ACF, custom post types, and 50 plugins. Anyone who quotes before auditing is guessing.
• They propose starting development before content extraction. The content extraction informs the CMS schema design, which informs the component architecture. Starting development before understanding your data is working backwards.
• They don't mention WooCommerce migration complexity. If your site has WooCommerce, the migration complexity roughly doubles. A provider who treats it as a footnote will underdeliver.
• They suggest keeping WordPress as a "headless" backend. While WordPress can be used as a headless CMS, this defeats most of the purpose of migrating. You still have WordPress maintenance, security patching, plugin updates, and database management — you just also have a separate frontend to maintain.

Realistic Timelines by Site Complexity

Simple marketing site (5-15 pages, no blog)

Timeline: 1-2 weeks. Migration is straightforward — extract content, build components, set up redirects. The limiting factor is usually client review, not development.

Business site with blog (15-50 pages, 50-500 posts)

Timeline: 2-4 weeks. Blog content migration and SEO preservation add significant scope. Custom post types and ACF fields require careful schema design. Content verification takes time with this volume.

Complex site with custom functionality (50+ pages, custom post types, integrations)

Timeline: 4-8 weeks. Custom functionality needs to be rebuilt or replaced. Third-party integrations (CRM, email marketing, analytics) need reconnecting. Thorough testing of custom workflows is essential.

WooCommerce store

Timeline: 6-12 weeks. Product migration, payment gateway setup, customer account migration, order history preservation, and checkout flow testing all take significant time. A phased launch approach adds 2-3 weeks but reduces risk.

Protecting Your SEO Equity During Migration

Your WordPress site's search rankings represent years of accumulated authority. Here's how to protect them:

1. Baseline your current rankings — export your Google Search Console data for the last 6 months. Document your top 50 pages by traffic and their current rankings for target keywords.
1. Map every URL change — create a spreadsheet with old URL in one column and new URL in the other. Every page should either keep its URL or have a 301 redirect.
1. Preserve meta data — export all Yoast/RankMath meta titles and descriptions. These should be identical (or improved) on the new site. Don't let them default to auto-generated values.
1. Submit the new sitemap immediately — within hours of launch, submit your new sitemap to Google Search Console. Request re-indexing of your most important pages.
1. Monitor daily for 2 weeks — watch for crawl errors, dropped pages, and unexpected ranking changes. React quickly to any issues.
1. Keep the old site accessible for 30 days — run it on a subdomain or alternate port as a reference. If something was missed during migration, you can recover it.

What "Done" Looks Like: Acceptance Criteria

Before signing off on a WordPress migration, verify these acceptance criteria:

Content Accuracy

• Every published WordPress post and page exists on the new site
• All rich text formatting is preserved (headings, lists, bold, italic, links)
• All images display correctly at all viewport sizes
• Custom fields (ACF, etc.) render correctly in the new templates
• Categories, tags, and custom taxonomies are intact

Performance

• Lighthouse Performance score above 90 on all key pages
• LCP under 2.5 seconds on mobile
• CLS under 0.1
• TTFB under 200ms

SEO

• 301 redirects for every changed URL (test with curl -I)
• Meta titles and descriptions preserved from Yoast/RankMath
• Sitemap generated and submitted to Google Search Console
• No 404 errors for previously indexed URLs
• robots.txt configured correctly

Functionality

• All forms submit successfully and reach correct destinations
• Third-party integrations working (analytics, CRM, email marketing)
• Search functionality returns relevant results
• RSS feed includes recent content

Deliverables

• Complete codebase in a Git repository you own
• CMS admin access with full control
• Documentation for deployment, content editing, and common changes
• DNS configuration guide or managed cutover

Don't rush this checklist. Take a full business day to verify everything with your team. It's far cheaper to catch a missing redirect before launch than to discover lost traffic two weeks later. A good migration provider will welcome your thoroughness — they want you to be confident in the result.
