Yes it is, this (http://smartgeeks.co.cc/wp/archives/199) is the guide I used.

This is what I did:

Booted jaunty live-cd on a system running jaunty and ext3 (on /dev/sda1 in my case), opened a terminal:

sudo bash
tune2fs -O extents,uninit_bg,dir_index /dev/sda1
e2fsck -pf /dev/sda1
mount -t ext4 /dev/sda1 /mnt
nano /mnt/etc/fstab

In fstab I changed "ext3" to "ext4" for the partition I converted (and saved the changes).

The distribution upgrade does not seem to install the new grub stage. So I did the following to refresh grub (again from a live-cd):

sudo bash
mount /dev/sda1 /mnt
grub-install /dev/sda --root-directory=/mnt --recheck
