Lesson

Hi there,
I know this thread is about importing lesson, but I'm having the same problem when I import a whole course. This thread was the closest I could find to my problem, so please excuse if it's not completely related.

I imported courses from 1.6 into 1.9 and all image links were broken. Just wondering, the course that I exported from 1.6 had a course id 55. In 1.9 it became course id 63. Is there a way to go in and change the course id from 63 back to 55? It seems like that would work - but I could be completely wrong as I am not a programmer. Thanks!
Barry
