How do I transition multiple installations to a single Multisite installation?

I have a client who runs 8 different blogs, currently on 8 separate installations of WordPress. I’m trying to encourage them to move to a single MS installation instead to make it easier (mostly on me) to maintain the different sites, themes, and mix of plug-ins. Unfortunately, I shied away from MU for the longest time, and now I have no idea where to start with MS.

Display featured products through custom loop in woocommerce on template page

I would like to display 6 featured products from my woocommerce store on my home-page.php template. After some researched I found that the right way to do this was through a custom loop,( I do not wish to use shortcodes because I would like to add additional classes for styling etc. ) I also found that the key that woocommerce uses for the featured products is ‘_featured’. I put together the code below to display any products that I chose to be featured products in my store, but it doesn’t work… Any help is appreciated.
