A standard HubSpot website migration takes two to eight weeks for most sites. Small sites under 30 pages typically complete in two to four weeks. Mid-sized sites with 50 to 200 pages require four to eight weeks. Complex migrations involving CRM data transfer alongside the website move can extend to eight to twelve weeks.
Timeline depends on four main variables: number of pages, level of redesign, CRM migration complexity, and internal approval speed. A straightforward lift-and-shift of a 20-page site where the design stays largely the same can finish in two to three weeks. A 100-page site with messaging overhaul, new conversion paths, and Salesforce-to-HubSpot CRM migration runs eight to twelve weeks. The internal bottleneck is usually content review and approvals. If your team takes two weeks to review template designs instead of three days, that delay cascades through the rest of the project. HubSpot's own replatforming team estimates 14 to 21 days for most migrations once all required assets are provided. Agency-led migrations with strategic components run longer because they include discovery, messaging workshops, and iterative design reviews that do not exist in a basic platform migration.
