It is not safe in general to upgrade a production installation directly. You must have a development environment in which to test the upgraded software or you will experience extensive downtime and probably end up reverting the upgrade several times while trying to get back to a working system. While extensive compatibility is provided for attribute, metadata, and relying-party configuration, authentication typically must be manually configured and you will need to test to ensure your particular configuration isn't using advanced features that may strain the compatibility provided. |
