# Updates

Each new version of the OUAF SDK installs to its own folder, allowing you to use several versions of the SDK on the same workstation. An OUAF SDK installation should never be used to overwrite an existing SDK installation with the intent of "upgrading" it. You should only develop using the version of the OUAF SDK that runs the same OUAF version that your application server runs.

New versions of the OUAF SDK can be installed and old versions uninstalled without affecting the application server. These options allow you to migrate your application servers to a newer version of the OUAF while allowing you to still refer to the original application server setup.
