Migrate existing Ext3 filesystems to Ext4

Before doing this, back-up all data on any ext3 partitions that are to be converted to ext4.

After running previous command you MUST run fsck, is needed to return the filesystem to a consistent state.

fsck -pDf /dev/yourpartition

Edit /etc/fstab and change the 'type' from ext3 to ext4 for any partitions that are converted to ext4.
