Move a Customized plan.xml File from the Oracle Fusion Middleware Home Installation Directory

Oracle SOA Cloud Service uses image-based patching, which means that the Oracle Fusion Middleware home installation directory is replaced with a new image when a patch upgrade occurs. Any post-installation configuration changes you make to the plan.xml file in the installation subdirectory ($MW_HOME/soa/soa/plan.xml) are overridden when upgrade patching occurs:

If you need to customize the plan.xml file after installation, ensure that you place this file outside the installation directory. Otherwise, patching overrides your changes.
