Step 4: Remove the current software version on the vEdge, It will start removing the software image on the vEdge which will take some time.
Step 5: Install the new software version as shown in the available version for the vEdge, This version is available on the vManage and vEdge will download this image from the vManage.
Step 6: As we started downloaded the new image for the vEdge and install the desired built on the vEdge, Now we need to activate the same image on the vEdge
Step 7: As we activate the software which will take reboot on the vEdge and come up with the new image after rebooting, Now set the default image to 19.2.31 as below
Now the new image is downloaded on the vEdge, installed, then rebooted, activated and then set the default image to the desired image. This is the whole process of downgrading the vEdge image via CLI commands.
