We need to take our SharePoint Enterprise 2010 instance's look-and-feel to a new 2013 instance. We didn't customize the master page but instead used page layouts in publishing pages to create the look we wanted for the sites. All the sites of our one site collection have publishing enabled.
We don't need to migrate the content (sites) to the 2013 instance. How do we export these custom page layouts and their CSS files, images, JavaScript (and anything else that is required) to 2013 from 2010?
Thanks.
