2. Download the Cisco IOS XE SD-WAN software image from the Cisco site.
3. Upload the Cisco IOS XE SD-WAN software image from the file server to the router bootflash. In this case the image is loaded on a USB flash drive and copied to the device.
4. If using bootstrap method, copy the configuration file to bootflash
5. If using bootstrap method and the enterprise root certificate, copy the certificate to bootflash
6. Remove all existing boot statements and save the configuration. You can check for existing statements using the command show run | i boot. If there is any statement, go to configuration mode and delete it using the no boot system command.
