Hi Chris, this is a great article.  With regards to web services, when you go to install the 2016 version on a server that already had 2015, it says "Folder is not empty".  I don't see an easy way to remove the 2015 version, so what I've been doing is adding a 2016 to the end of the folder name.  There is probably a better way, I just haven't found it yet.
