Hello,
We are able to finish an upgrade to 2.6. I am currently trying to restore a large course (170MB) from 2.2 into 2.6 Until now, we have not had any issues.
I can get all the way through the process but then Moodle gives me an "Error writing to the database" message and returns me to the home screen.
When we try to deselect different sections to backup on 2.2, it will go very slowly and will give a script error message from time to time with the browser (firefox and chrome) wanting me to kill or end the page.
Any thoughts? I saw there was a way to unzip files and bring it in, but when I try to do that with this course I get too many folders to know how to proceed.
