I have been testing a Moodle 1.9.17 to 2.2.3 upgrade for one of our large college clients (with one of the biggest college moodles in the UK).
They are getting two problems that are preventing the upgrade from being successful. Firstly, when it gets to the mod_quiz section of the upgrade (which is being run from the command line), the upgrade process throws out a very large number of errors of the following form:
Shortly followed by:
and then a short while later, it does the whole thing again (with different session and question numbers). There must be thirty or more of these.
Does this represent a real problem, or is it just reporting the actual state of the database and thus we are no worse off than before?
