If you have multiple blogs within HubSpot, you can easily move a blog post from one blog to another. To do this, follow the instructions below:
In your HubSpot account, navigate to Marketing > Website > Blog.
Hover your mouse over the blog post you want to move and click Edit.
Click the Settings tab.
In the Blog URL section, click the pencil icon edit next to your blog URL. You'll see a dialog box with information about how redirects are handled when you edit the URL of a live post. Click Update to confirm you want to edit the URL.
Use the Blog URL dropdown to select the blog you want to move your post to.
Click Save or Publish to finish moving your blog post.
