CloudEOS and vEOS Upgrade/Downgrade
The CloudEOS and vEOS images are upgraded/downgraded just like any other Arista switch by copying the desired CloudEOS.swi file to /mnt/flash. Configure the boot system flash:CloudEOS.swi, and then reload the VM from the Arista CLI. For more information, refer https://www.arista.com/en/um-eos/eos-upgrades-and-downgrades. Note, while upgrading your existing vEOS Router image to CloudEOS Router image, use .swi as the file extension.
