Hiring a Developer to Migrate Your HubSpot Site: What to Expect

Why HubSpot CMS Migrations Require Specialized Knowledge

Not all website migrations are equal. A HubSpot CMS migration has specific challenges that set it apart from migrating WordPress, Squarespace, or Webflow. The provider you choose must understand these challenges — or they'll underdeliver, miss critical integration points, or lose content that matters.

The unique aspects of HubSpot CMS migration include: extracting content from HubSpot's proprietary API structure, understanding HubL template architecture, preserving CRM data flow (forms, tracking, workflows), handling HubDB data, and maintaining the HubSpot ecosystem integration after the CMS changes. A general web developer who has never worked with HubSpot will struggle with at least three of these.

What to Look for in a Migration Partner

HubSpot API Familiarity

Your migration partner needs hands-on experience with HubSpot's APIs. They should know the difference between the CMS API (for page and blog content), the HubDB API (for structured data), the Files API (for assets), the Forms API (for form submissions from external sites), and the CRM API (for contact management). Ask them to describe their content extraction process — a good answer references specific API endpoints, pagination handling, and rate limit management.

CRM Integration Experience

The most critical aspect of a HubSpot CMS migration isn't the CMS — it's maintaining CRM connectivity. Your forms need to create contacts. Your tracking script needs to fire. Your workflows need to trigger. Your lead scoring needs to work. A provider who treats the CRM integration as an afterthought will deliver a beautiful website that breaks your sales pipeline.

Ask specifically: 'How will you ensure that form submissions from the new site create HubSpot contacts and trigger the same workflows they do today?' The answer should reference either HubSpot form embeds (the simple path) or the Forms API / Contacts API (the custom path) — not hand-waving about 'connecting things up later.'

Understanding of HubL and Design Manager

Your migration partner doesn't need to be a HubL expert — they're building React, not HubL. But they need to understand HubL well enough to interpret your existing templates. They should be able to look at a HubL template, understand its layout structure, identify the custom modules and their field definitions, and translate that into a component architecture for your new stack.

The red flag: a provider who says they'll 'scrape the website' instead of using the API. Scraping captures the rendered HTML but loses the content structure, metadata, and template-level organization. It's the lazy path, and the result is messy content that's hard to maintain in your new CMS.

Modern Frontend Expertise

The target platform matters as much as the source. Your provider should be proficient in your target stack — whether that's Next.js, Astro, Remix, or another modern framework. They should know how to set up a headless CMS, implement ISR or static generation, configure image optimization, and deploy to modern hosting platforms (Vercel, Cloudflare, etc.).

Agency vs Freelancer for HubSpot Migrations

Agency

A web development agency assigns a team: project manager, developer, possibly QA. You get structured processes, documented deliverables, and accountability.

• Cost: $10,000-30,000+ depending on complexity
• Timeline: 4-8 weeks
• Strengths: process maturity, multiple skill sets, post-launch support, contract protection
• Weaknesses: higher cost, communication through PM layer, potential for scope creep, may lack specific HubSpot experience

Important: most web agencies are not HubSpot migration specialists. Many are HubSpot partners who build on HubSpot, not away from it. Make sure the agency has experience migrating from HubSpot, not just building HubSpot sites.

Freelancer

A solo developer handles everything directly. Communication is faster, costs are lower, and you're working with the person who writes the code.

• Cost: $3,000-15,000
• Timeline: 2-5 weeks
• Strengths: direct communication, faster iteration, lower overhead, often more hands-on expertise
• Weaknesses: single point of failure, capacity constraints, limited availability for post-launch support

For freelancers, vetting is especially important. Ask for a specific HubSpot migration example — not just 'I've built Next.js sites' but 'I've migrated a HubSpot CMS site to Next.js and here's the result.' The HubSpot-specific knowledge (API extraction, CRM integration preservation, HubDB migration) is what separates a qualified freelancer from one who's guessing.

AI-Assisted Migration Service

A migration specialist who leverages AI coding tools to accelerate development. Human expertise drives strategy and quality; AI handles the volume of code generation.

• Cost: $3,000-10,000
• Timeline: 1-3 weeks
• Strengths: fast turnaround, consistent code quality, purpose-built for migration, result is AI-maintainable
• Weaknesses: newer service category, less suitable for heavily custom design work

Red Flags During the Evaluation

Watch for these warning signs when evaluating potential HubSpot migration providers:

• They don't ask about your HubSpot CRM integration. If the first conversation doesn't include questions about which CRM features your website uses (forms, tracking, workflows, chat), they're treating it as a simple CMS migration. It's not. HubSpot CRM integration is the critical path.
• They propose scraping your website. Scraping captures rendered HTML but loses content structure, metadata, HubDB relationships, and module-level organization. The API-based approach is slower to set up but produces dramatically better results.
• They've never used the HubSpot CMS API. HubSpot's API has quirks — the difference between site-pages and landing-pages endpoints, the layoutSections structure for drag-and-drop pages, the pagination cursor system. A provider who hasn't used these APIs will spend your budget learning them.
• They don't mention HubDB. If your site uses HubDB and the provider doesn't bring it up, they haven't audited your site properly. HubDB data migration requires specific API knowledge and schema mapping work.
• They suggest staying on HubSpot 'headlessly.' Using HubSpot CMS as a headless content source is technically possible but defeats the purpose — you still pay the CMS subscription, still use HubL for content modeling, and still have the vendor lock-in. The whole point of migrating is to leave the CMS tier.
• They give a fixed quote without auditing your site. HubSpot CMS migration complexity varies 5x between a simple brochure site and a site with HubDB, custom modules, smart content, and heavy CRM integration. A credible estimate requires examining your actual site.

Questions to Ask Potential Providers

These questions are calibrated specifically for HubSpot CMS migrations. The quality of the answers reveals genuine experience:

"How do you extract content from HubSpot CMS pages built with the drag-and-drop editor?"

Good answer: describes using the Pages API and parsing the layoutSections object to extract content from each module, then transforming that structured data into the new CMS format. Mentions handling different module types (rich text, image, form, custom modules) differently. Bad answer: 'We export the HTML.' That captures rendered output but loses the structured content that makes migration clean.

"How will forms continue to create HubSpot contacts after migration?"

Good answer: describes two approaches — embedding HubSpot forms via their JavaScript API (simpler) or building custom forms that POST to the HubSpot Forms API endpoint (/submissions/v3/integration/submit/{portalId}/{formGuid}). Explains which approach they recommend and why. Bad answer: 'We'll set up the forms on the new site.' That doesn't address the CRM integration specifically.

"What happens to our HubSpot marketing workflows after migration?"

Good answer: explains that workflows trigger off CRM events (contact creation, property changes, form submissions), not CMS events. As long as the new site feeds the same data into HubSpot CRM via API, all existing workflows continue functioning without modification. They should also mention verifying workflow triggers with test submissions before launch. Bad answer: 'Workflows are separate from the CMS.' Technically true but doesn't explain how they'll verify continuity.

"How do you handle HubDB data migration?"

Good answer: describes exporting HubDB tables via the API, mapping column definitions to new CMS field types, transforming row data, and importing into new CMS collections. Mentions handling special column types (images, foreign table references, select options). Bad answer: 'What's HubDB?' If they don't know what HubDB is and your site uses it, they're not the right provider.

"Can you show me a HubSpot CMS migration you've completed?"

The most important question. A provider with real HubSpot CMS migration experience can show before/after, discuss specific challenges they encountered (API pagination, layoutSections parsing, CRM integration), and demonstrate that the CRM features survived the migration. If they can only show Next.js builds without HubSpot source experience, they're learning on your project.

Realistic Timelines

HubSpot CMS migrations are generally faster than WordPress migrations because HubSpot's content is more structured and the API extraction is cleaner. Here are realistic timelines:

• Simple site (5-15 pages, no blog, basic forms): 1-2 weeks
• Marketing site with blog (15-50 pages, 100+ posts, CRM forms): 2-4 weeks
• Complex site (50+ pages, HubDB, custom modules, heavy CRM integration): 4-6 weeks
• Enterprise site (knowledge base, multiple blogs, memberships, serverless functions): 6-10 weeks

These timelines assume a focused migration effort with prompt client review. The biggest variable is stakeholder feedback — technical work rarely stalls, but waiting for client review at each checkpoint adds 30-50% to the total timeline.

What the Deliverables Should Include

Before signing an agreement, confirm the deliverables include:

• Complete content migration: all blog posts, pages, and HubDB data in the new CMS with metadata intact
• Component library: React components for every page template and custom module, built on your new CMS
• HubSpot CRM integration: forms submitting to HubSpot, tracking script installed, workflows verified
• 301 redirect map: every changed URL redirects properly, tested and verified
• SEO preservation: meta titles, descriptions, canonical URLs, OG data, and sitemap
• Git repository: complete source code in a repo you own with deployment documentation
• CMS admin access: full admin access to your new CMS with documentation for common content tasks
• Post-launch support: 30-day period for bug fixes and issues discovered after launch

How to Evaluate Proposals

When comparing proposals from different providers, score them on these criteria (in order of importance):

1. HubSpot CRM integration plan. The proposal should explicitly describe how forms, tracking, and workflows will work after migration. If this isn't detailed, the provider hasn't thought it through.
1. Content extraction methodology. API-based extraction with specific endpoint references is good. "We'll export your content" without detail is bad.
1. SEO migration plan. Redirect mapping, meta data preservation, sitemap submission, and post-launch monitoring should all be mentioned.
1. Timeline realism. Compare to the timelines in this article. A proposal promising a complex migration in 1 week is either cutting corners or doesn't understand the scope.
1. Portfolio relevance. Prior HubSpot CMS migration work is worth 10x more than general web development experience.
1. Price. Last, not first. A cheap migration that breaks your CRM integration or loses content costs far more than a properly scoped migration at a higher price.

Maintaining CRM Integration Post-Migration

After migration, your HubSpot CRM integration needs ongoing attention:

• Monitor form submissions: verify that forms on the new site consistently create contacts in HubSpot. Check weekly for the first month.
• Verify tracking data: compare page view data in HubSpot analytics before and after migration. A significant drop means the tracking script isn't firing correctly on all pages.
• Test workflows regularly: submit test forms and follow the automation chain. Verify that lifecycle stage changes, email sequences, and internal notifications trigger correctly.
• Update HubSpot domain settings: in HubSpot settings, update your domain to reflect the new hosting. This ensures that HubSpot's tracking and reporting attribute traffic to the correct domain.
• Keep the HubSpot tracking code updated: HubSpot occasionally updates their tracking script. Include it via the official embed method (not a copy-pasted script) so updates apply automatically.

A well-executed HubSpot CMS migration doesn't feel like leaving HubSpot — it feels like upgrading your website while keeping your CRM exactly as it was. The sales team sees the same contacts, the same workflows, the same deal pipeline. The marketing team sees better page speed, lower costs, and more design flexibility. That's the outcome you should demand from any migration provider.
