Before You Upgrade the Software on a C-series Controller
Before you upgrade system software on a C-series Controller:
- Create a snapshot of the software files currently on the C-series Controller.
See Creating a Snapshot of Files on a C-series Controller.
- Make sure that other C-series Controllers can carry system load during the upgrade. The system will not be operational during the upgrade.
