We have been using moodle for quite a few years. In 2010? we installed a newer version and exported and imported the data to the new version 2.3.1. This seemed to go smoothly, with the main issue being a few font problems.
Now we are looking to do another update and have been working with a developer to update to 3.4.2. We seem to be having an incredible number of problems. He has been working, very part-time, on this update for more than 8 months now and every step forward seems to include a few steps back, e.g. quizzes weren't working properly, so he made some changes and now a significant percentage of the metalinks don't work, etc, etc, etc.
I have 3 questions
1. Is this to be expected?
2. Is he not familiar enough with moodle and causing unnecessary problems?
3. Would we be better off starting over or choosing another option? This would be a very big undertaking.
In essence, I'm wondering if the problem is the task or the programmer. Please offer opinions or other information.
