Manual steps to be done when upgrading from DG3 0.11.x to 0.12.x
The major change between DG3 0.11 and 0.12 is support for more than one internal web server. Now we support nginx and lighttpd as deployment web server for DG3. All you have to do to switch between them is a setting in web server settings. Default server for now is lighttpd as this was the original supported web server, but that might change at a later time if you chose not to set anything. The nginx seams to be as fast and lightweight as lighttpd but sees a lot more active development and also seam to support a better way to grow with you DG3 solution than the lightttpd web server.
This is what you have to do when you upgrade
Select web server settings and review you selection. Save the settings even if you do not do any changes. Now you are ready to rebuild you solution and redeploy it to the server.
