I am still using Moodle 1.6.2 and 1.6.3 from 2006 for online quizzes, and assignments. It works well but alas it is not fully adapted to secure, encoded https so "modern" browsers keep telling the students that the site is insecure. Our system staff tell me that if the server is upgraded to provide full https (not only on the login page) then older versions of Moodle will not work.
The problem with upgrading, or moving to the university installation, for me is that on my 1.6.2/3 I have a date changing functionality via the course date manager that lets me change all the dates of the quizzes by 6 months or a year and then change subsets of the quizzes by a week or so to move their to match the new semester with its different holidays and make up-days, and then tweak a few more to absolute dates all on the same page.
I understand that the core can now update courses changing all the dates, but I don't think that the current date module has the functionality to change a subset of the dates at once.
I see that there is a date manager for quizzes only kindly provided by for Moodle 2.2. which is probably https compatible
Is there any other way of obtaining a course date changer type functionality on current versions 3.7/8? of moodle?
