Promote SharePoint Subsite To Main Site

template the site and create a new site using the template.

Thank you! Will that also move the data that's on the site?  It's a blog.

Yes, you can include the content.

Here's a guide:

Awesome thank you.  I followed the steps, and I was able to create the site from the template.  However, it just created an additional subsite alongside the site I made the template from.  Is it possible that this method is for transferring a site between collections and not from subsite to main site? I am probably just looking at this all wrong, and I may have even asked my original question incorrectly.  I have a main site with addresses similar to "something.sharepoint.com/sitepages/home.aspx".  /sitepages/home.aspx is currently the landing page when someone goes to "something.sharepoint.com".  My blog is addressed similar to this "something.sharepoint.com/blog".  This is where I would like to direct users when they go to "something.sharepoint.com".  I thought that I might be able to migrate the blog into the "sitepage" directory, and then I could just use the "Make Homepage" button to accomplish this, but I am not seeing how to do that (or if that is even what I should do).  Should I go ahead and award points for this question and then make a new one with my above question?  Thank you.

Thanks!

my pleasure :)
