To upgrade, you first need to purchase and download the Focus Plus theme from the HubSpot Marketplace.
Once installed, you must apply it to your website by manually opening your existing pages, switching their templates to the Focus Plus versions, and replacing the old Focus modules with the new Focus Plus modules. HubSpot does not offer an automatic migration tool, so this transfer must be done page by page.
That's why we highly recommend starting directly with Focus Plus after testing the free version to save time and effort.
