Backup Files
When you upgrade your system, the tool creates a backup version of the original file and stores the file in the same
directory as the original file. The backup file has the same name as the original file; however, the backup file has a
.bak extension. To use the backup file, you need to remove the extension from the file name.
Note: The default location of a .caf file is C:Usersusername.
Steps
Upgrading a System
Note: The tool automatically creates a backup of the .caf file before upgrading it. See the Backup Files section if
you need to revert to the saved backup file, or for more information.
To upgrade a system:
1. From the File menu, select Open.
2. Select the .caf file that requires the upgrade and click OK. One of two dialog boxes appears, depending on
whether the file you selected requires module upgrades:
• If the file requires module upgrades, a dialog box appears displaying a list of standard and user-defined
modules. Standard modules are included as part of the upgrade process. For more information about these
standard modules, see Upgraded Modules.
• If the file does not require module upgrades, a smaller dialog box appears prompting you to upgrade the
system.
3. Click OK. The tool upgrades the system to the latest version.
Note: After the upgrade, you must command points back to the previous state. Commands do not persist in the
control application file, and when the application downloads, the previous application is deleted from the
controller.
