For this next part of the process I copied my Moodle 1.9 installation to a local development server. But to save time I didn’t copy the entire MoodleData folder as it’s over 160GB. I only copied the first 20 folders.
As I wouldn’t be using LDAP on this test server (yet!) I changed my admin account to a manual account so I didn’t lock myself out.
I then flushed out the htdocs folder and copied the Moodle 2.0 installation files across so that I had a clean install with no modifications and ran the install script.
