Upgrading from OpenCms 7.x
About this tutorial
OpenCms 8 introduces a lot of great new concepts and functionality that content managers certainly don’t want to miss. While OpenCms 8 is fully backward compatible, to make full use of these new features, existing OpenCms sites need to be adapted for the new technology.
This tutorial shows how to gradually upgrade an existing OpenCms installation to OpenCms 8. It explains how to use existing OpenCms 7 Templates in an OpenCms 8 installation. How to use templates of the old and the new technology together is presented, too. Strategies for a migration of existing templates and content so that they can make full use of the OpenCms 8 features get also shown.
This tutorial also explains the benefits of upgrading to OpenCms 8 even when staying with the old templates, as OpenCms 8 provides a much improved publishing dialog, support for mobile devices, extended content subscription, support for xsd:choice in the XML content editor , HTML 5 based multiple file upload and improved content galleries . All these features are usable without changing the templates or content structure of an existing OpenCms installation.
