Can we migrate our site to HubSpot in phases or does it have to happen all at once?

A phased migration is fully supported and often recommended. Many companies start by migrating their blog or landing pages to HubSpot first, then move the core website in a later phase. This approach reduces risk, spreads the workload, and allows your team to learn the platform before the full cutover.

The phased approach works well for teams with limited bandwidth or complex sites. A common sequence starts with blog migration (lowest risk, highest SEO sensitivity), followed by landing pages and forms (directly tied to lead generation), and finally the main website pages. During the phased period, your original site stays live on its current platform while migrated sections point to HubSpot. The tradeoff is that running two platforms simultaneously requires careful DNS configuration and can create inconsistencies in analytics tracking across domains. If your team has multiple people regularly editing the site, it helps to pause non-essential site updates during each migration phase so the target content does not drift from what was scoped. A full cutover migration can be faster when the site is smaller (under 50 pages) and the team has capacity to absorb the transition in a compressed window.
