Almost all platforms are moved over to the FIT format. This transition should be harmless.
One known issue is the data partition is moved thus if upgrading from a pre-FIT image to a post-FIT image, one needs to first remount /mnt/data as read-only and then upgrade using flashcp/fw-util. After reboot the contents in /mnt/data might be lost. So, a backup might be required.
