Thinking about migrating to HubSpot CMS? Making the switch is a big decision, and you're right to be thorough. We've guided dozens of companies through this process, and we'll help you get it right. Start by deciding whether moving the website to HubSpot is the right choice for your team.
A HubSpot CMS migration makes sense when the current system is difficult to update or maintain, or when the marketing team wants the website, forms, CRM, and reporting to work more closely together. HubSpot's Replatforming service is best suited to a mostly like-for-like move.
A partner-led project is more useful when the migration also involves design, content, integration, or functionality changes. Keeping the current CMS can also be the right choice when the team can maintain it securely and use it comfortably.
HubSpot's website content management tools are part of Content Hub. A migration moves website pages, blog content, templates, images, forms, tracking, and other required assets from the current platform into HubSpot. The project may preserve the current design, or it may include a redesign and content changes.
The right scope depends on what the current site contains and what the team expects to change. HubSpot describes four ways to move a website to Content Hub: use a marketplace theme and import tools, use an internal development team, hire a Solutions Partner, or use HubSpot's Website Migration service.
| Approach | Best fit | What to consider |
|---|---|---|
| HubSpot's website migration service | You want to copy your website to HubSpot verbatim. | HubSpot recreates content and styling in a HubSpot theme. Review the migration agreement carefully because custom functionality and some content types may not be included. |
| Partner-led migration or redesign | You want to migrate while changing design, content, integrations, or functionality. | A partner can plan the full project, rebuild features that will not move as-is, and coordinate content, SEO, analytics, testing, and launch. |
| Keep the current CMS | Your team can maintain the platform securely, update it comfortably, and connect it with HubSpot. | Staying put may avoid unnecessary risk and preserve functionality or infrastructure your company wants to control. |
HubSpot's current Replatforming documentation explains that its service is intended to recreate existing content in a HubSpot or marketplace theme. It also identifies features that are not expected to migrate, including database-driven content, gated experiences, e-commerce, advanced forms, and some third-party applications.
Keeping the existing CMS may make sense when:
A company can use HubSpot without hosting the entire website there. Our guide to using HubSpot and WordPress together explains how forms, tracking, calls to action, chat, and other tools can work with an existing WordPress site.
HubSpot can reduce the number of separate systems a marketing team has to manage and make routine website work easier. The practical benefits depend on the subscription and configuration, but commonly include:
HubSpot's current Product Specific Terms state a 99.95% service-uptime commitment for paid subscriptions. Healthcare organizations should also evaluate subscription eligibility, configuration, and the Business Associate Agreement before storing protected health information. HubSpot documents its Sensitive Data requirements for Content Hub Enterprise; using HubSpot does not automatically make every website HIPAA-compliant.
We start by collecting enough information to find the gotchas before experiencing them. If we are moving a website from another server or CMS to HubSpot, we run a website crawler that finds every address it can reach and records details such as page titles, meta descriptions and functionality that might not be native to HubSpot.
We also get access to the systems needed to understand, build, and validate the migration:
Access to the current CMS matters because a crawler cannot always find everything. Landing pages, thank-you pages, downloads, old campaign content, unpublished templates, redirect rules, or pages that are not linked in navigation may still need to move or be accounted for.
Once the inventory and access are in place, we decide what will move, what will change, and how each important function will work in HubSpot. If the project also includes a redesign, it helps to separate design and content decisions from the technical migration work. Our website redesign process explains the business, measurement, content, and technology decisions that belong in that plan.
| Phase | What happens | What the team approves |
|---|---|---|
| 1. Audit and discovery | Crawl the site, inspect the CMS, document templates, content, forms, integrations, tracking, functionality, and search performance. | Project goals, required access, constraints, and decision owners |
| 2. Scope and mapping | Decide what to keep, change, combine, retire, or rebuild; map old URLs to final destinations; define the test plan. | Sitemap, content decisions, design direction, functionality plan, and URL redirect map |
| 3. Build and migrate | Create templates and modules, move content and media, configure forms and integrations, and implement tracking. | Representative templates, modules, content, and functional behavior |
| 4. Quality assurance | Test pages, navigation, responsive layouts, forms, integrations, downloads, redirects, metadata, analytics, and permissions. | User acceptance, launch checklist, and issue resolution |
| 5. Launch and validate | Connect the domain, remove temporary crawl blocks, run a post-launch crawl, verify tracking and forms, submit the sitemap, and monitor issues. | Launch completion, training, and post-launch ownership |
A content freeze or clearly managed change process is important once migration work begins. HubSpot notes that changes made to the existing site after its migration has been approved will not automatically appear in the migrated content. A partner-led project also needs a way to track late edits so they are not lost between environments.
A CMS migration should preserve the search engine optimization aspects the website already has. Start with a crawl and analytics baseline, then account for important URLs, page titles, meta descriptions, canonical tags, structured data, internal links, images, downloads, robots directives, and Search Console verification.
If URLs change, Google's site-move guidance recommends mapping old URLs to relevant new destinations, using permanent server-side redirects (which are easy to add on HubSpot), avoiding redirect chains, updating internal links and canonical tags, and submitting the new sitemap. If the visible URLs stay the same, follow Google's hosting-change guidance to test the new environment, preserve verification, remove temporary crawl blocks, update DNS, and monitor traffic and crawling.
Search rankings may fluctuate while Google recrawls and processes the move. Monitor Google Search Console, the post-launch crawl, analytics, forms, and priority conversion paths until the site is stable.
The same safeguards help AI-search visibility. Important answer content must remain visible and crawlable, structured data must still match the page, and internal links should continue to show how related topics and services connect. A migration should not discard those signals simply because the pages have a new CMS behind them.
Page count matters, but it is not the only driver. Templates, custom functionality, integrations, content changes, URL redirection, approval cycles, training, and testing can affect both the estimate and the schedule.
Based on Whittington Consulting's current project estimates as of August 2026:
| Website scope | Typical planning range | Typical timeline |
|---|---|---|
| Small site, often 10–50 pages | $5,000–$10,000 | About 3–5 weeks |
| Mid-sized site, often 50–200 pages | $10,000–$15,000 | About 5–8 weeks |
| Large or complex site, often 200–1,000+ pages | $15,000–$20,000+ | About 6–10 weeks or longer |
These are planning ranges, not quotes. They generally cover development and migration, content migration, and training, but the final scope determines what is included. HubSpot subscription fees and any paid themes, applications, or other products are additional.
Build the business case from the costs and problems the company actually has: developer time, hosting and maintenance, overlapping tools, slow publishing, unreliable tracking, weak conversion paths, or functionality that prevents the team from doing its work.
After launch, compare those baselines with publishing time, maintenance demands, site errors, organic traffic, form performance, lead quality, and the sales opportunities connected to the website.
Not all HubSpot partners approach website work the same way. Ask how the team handles the parts of the project that matter to your website:
Be cautious when the scope is based only on page count, the partner cannot explain how redirects and testing will work, or responsibilities are unclear. Those gaps often become change orders, delays, or launch problems.
Whittington Consulting helps B2B companies, healthcare providers, and senior living organizations make their websites easier to operate and more useful to marketing and sales. Our migration work brings together HubSpot development, content, SEO, analytics, forms, integrations, quality assurance, training, and launch planning.
We start by asking questions, inspecting the current website, and creating a plan for what will move and how it will be validated. That preparation helps the team understand the real scope before work begins and gives everyone a clearer standard for deciding whether the migration is ready to launch.
A successful migration starts with an honest decision about fit. HubSpot replatforming may be enough for a website move with no design or copy changes. A partner can help when the project also needs redesign, content, integration, or custom functionality work. Keeping the current CMS may be the right answer when the team can maintain it securely and connect it with HubSpot.
