+Post Upgrade Procedures
+------------------------
+
+After upgrading CloudStack packages, new system properties and settings may be 
+introduced in the release. CloudStack will not overwrite or replace your existing
+configuration files. The latest configuration file are named with .rpmnew or .dpkg-dist 
+extention depends on your package manager. 
+
+It is strongly recommended to review and apply these new changes manually by comparing 
+them to your previously installed version.
+
+
+The locations of the essential configuration properties files are as follows:
+
+.. parsed-literal::
+
+   /etc/default/cloudstack-management
+   /etc/default/cloudstack-usage
+   /etc/cloudstack/management/db.properties
+   /etc/cloudstack/management/config.json
