ext2 and ext3 are basically the same thing except ext3 adds a journal.
It is extremely easy to convert an ext2 file system to ext3:
1) Make sure you have ext3 support compiled into your kernel.
2) In fstab, look for the line(s) for the filesystem you want to convert
to ext3. They will likely have ext2 as their type. Change this to ext3
or auto. The advantage of auto is just in case you ever compile a
kernel and forget to select ext3 support, this way you'll still be able
to boot your file system.
3) Run the command: tune2fs -j /dev/<partition here> for each ext2
partition you wish to convert to ext3.
Run man tune2fs for more/better information.
Hope this helps ya...
