How do I change my current location that I am backing up to (disk) to a new location? The Storage device is being replaced

We are currently using a Compellent Stirage array that is connected via Fiber Channel, I added 500 GB of disk space to the actual NetVault Server to use as a Target . We only back up a FileServer and an Exchange Database currently and never have more than 25 GB of BackUps. We have SmartDisk that is loaded on the Server, However, I cannot figure out how to create either a New Target or change the SmartDisk to point to the new location
