Can I copy a page from my old website?

Yes. Open Site Assistant in the website editor and pick the Scrape a Page tab. Paste the address of one page on any public website and it comes across as a draft page on your site: the words in their written order, the photographs where they sit (each one added to your Assets), and the page's search title and description.

The Notes field tells the assistant what to make from the page. It can rewrite the page's text (shorten the intro, drop the prices, write it in the first person), create article types, and turn the links the page holds into articles. For example: "create a type called Press and make each article linked under Publications an external Press article" reads the page and plans one draft article per linked publication. Instructions like that open as an import plan under Imports: you see exactly what will be made, untick anything, and run it. Leave the Notes empty to bring the page across exactly as written.

It arrives as a draft, so nothing on your live site changes until you review and publish it. To move a whole site at once, with every page and blog post, use a full migration instead.
