## Uninstalling Previous Versions of Sun Management Center Software

> If you have Sun Enterprise SyMONTM 2.x component layers already installed on your system, the install script allows you to uninstall the previously installed packages. You can either:

- Uninstall immediately and proceed with a fresh installation, or
- Quit the current session and uninstall the necessary packages automatically by using the `es-uninst` command, and then proceed with the installation.

> If you have Sun Management Center 2.x component layers already installed on your system, the install script prompts you to manually uninstall the previously installed packages.

> Refer to the Sun Management Center Software Installation Guide for more details.

> > Caution - Be aware that when you answer `y` to the uninstall prompt, your current Sun Enterprise SyMON 2.x or Sun Management Center 2.x packages will be uninstalled. However, the administrative domain information, custom alarm settings, and so on are retained in the `/var/opt/SUNWsymon` directory and may be used by the new installation.
