No, you'll have to go into the Unraid web interface, open the docker tab, click the motionEye icon and select "edit" from the dropdown. In this form find the "Repository" field and change "malvarez00/docker-motioneye" to "aartr/docker-motioneye" and press apply. This should go totally seamless but I'd recommend backing up your "motionEye" folder inside of your appdata just to be safe.
