Is there any way to conver ext4 to ext3 filesystem without formatting the partition/disk ..

Had ext3 filesystem and had converted it to ext4 by issuing following command

# tune2fs -O extents,uninit_bg,dir_index /dev/sda1
# fsck -pf /dev/sda1
# blkid /dev/sda1
/dev/sda1: UUID="d90d719a-af91-41fd-a337-12d1d1b2aa82" TYPE="ext4"

Now I want to convert it back to ext3 but no luck !

Unfortunately, it requires a lot of work on your part.
