I've come across a problem when tried to restore some old 1.9 moodle courses to 2.5; it actually restored them exception for activities issues (no users information needed). I only need to restore eigth courses so I may simply create activities from the scratch (copy contents).
I think this process will be harderless than upgrating four or five times! Other chance seems to use a converter tool. But Conversionthingy or NZ Moodle program didn work for me.
What would u recommend? Thanks.
