Hi Bret, many thanks for the reply.
Perhaps I have missing something, but where in any of the Upgrade docs does it say you need to have copies of the database + moodledata folder?
To clarify, I'm not making a copy of my site, I'm just trying to upgrade the current Moodle system from 1.9 to 2.2.
The upgrade documents state you must download the version you want/are capable of upgrading to (in my case, 2.2), rename your current moodle folder to something else, upload the new moodle files into a folder named as it was previously, then copy across the config.php from the old installation to start the upgrade.
The config.php file from 1.9 does not work when you copy it across (with all of the current details) into the new 2.2 directory. I had to use the format of the config file found in config-dist.php for 2.2, and place in the values accordingly (that file is just a shell, obviously.)
But instead of loading the Upgrade procedure, it just treats it as a new installation, almost like it's ignoring the config.php, and attempts a blank installation of 2.2.
Cheers
