A HubSpot website migration typically requires 15 to 30 hours of internal team time spread across four to eight weeks, primarily for content review, feedback on designs, and post-launch verification. The agency or HubSpot's migration team handles the heavy technical work, but your team owns approvals, content decisions, and user acceptance testing.
Internal time concentrates in three phases. During scoping, your team provides brand assets, access credentials, content priorities, and feedback on which pages to redesign versus migrate as-is. This takes roughly five to eight hours across a few sessions. During the build phase, your team reviews template designs and page drafts, flags content changes, and approves the staged site before launch. Budget eight to twelve hours for review rounds. After launch, your team verifies pages, tests forms, checks workflows, and monitors analytics for the first two weeks, which takes another five to ten hours. If your team regularly edits the site, it is best to pause non-essential updates during the migration phase so the content being migrated does not change underneath the project. Lean Labs provides one-on-one training and 90-day ongoing support after migration so your team can confidently manage the site independently.
