Perhaps a forum mod can merge the two. Barring that you can copy paste all the information from the original journal to the new one, editing the first post of the new journal and adding it as previous entries and put a link from the former to the current. That way it can still be a comprehensive journal if ic all the information is contained in a single journal. There are limitations to the size of a single post so it might not all fit, though with some creative editing it might be made to work by editing the first few posts of the new journal and moving things down.
