Caution: Always back up the switch configuration file before you upgrade or downgrade the switch software to avoid losing the configuration stored in nonvolatile RAM (NVRAM). When you downgrade switch software, you lose your configuration. Use the write network command or the copy config tftp command to back up your configuration to a Trivial File Transfer Protocol (TFTP) server. Use the copy config flash command to back up the configuration to a Flash memory device.
