Change default homepage for Adobe CQ5.6 Author

Problem

In Adobe AEM/CQ 5.6 Author instance is new homepage with new touch-friendly interface. However, as developer I prefer the old one that lies on /welcome.html. So how can the homepage be changed?

Solution

1. Open CRX Explorer Interface http://localhost:4502/crx/explorer/browser/index.jsp
2. Go to /libs/cq/core/config.author/com.day.cq.commons.servlets.RootMappingServlet
3. Right click the rootmapping.target property and select edit. Change the value to /welcome.html
4. Click save all.
