A HubSpot portal migration transfers CRM data (contacts, companies, deals, custom objects, workflows, and settings) between HubSpot accounts or from another CRM into HubSpot. A HubSpot website migration moves your front-end site (pages, blog, templates, and design) into HubSpot's CMS. They are separate workstreams that often run in parallel but address different systems.
Portal migration focuses on the backend: mapping data fields, importing records, rebuilding automation workflows, and configuring pipelines and lifecycle stages. This is the work of aligning how your business tracks and manages customer relationships. Website migration focuses on the frontend: recreating page layouts in HubSpot templates, moving blog content, setting up URL redirects, and configuring domain settings. A company switching from Salesforce to HubSpot CRM while also moving their WordPress site to HubSpot CMS would run both migrations simultaneously. The portal migration handles deal records, contact history, and sales automation. The website migration handles page design, content, and SEO preservation. Combined CRM and CMS migrations typically take 6 to 12 weeks depending on data volume and site complexity.
