You do not need to reformat your drives to go from ext2 to ext3. The underlying data is the same, so all you have to do in activate the journaling capabilities of the newer system.
There are any number of pages that describe the process, just google "convert ext2 to ext3"
AFAIK, this is a risk free process.
You can also do the same to go to ext4, but you do not gain all of the advantages without a reformat.
