Installing and upgrading help

If you start with a fresh install of 2.4 you won't be able to bring in your user data from your 1.9 Moodle so if that was essential to you then you'd have to upgrade from 1.9 upwards.

To add the confusion ...

Migration of the site is the only way users/assignments/etc. come along upwards.  But, even during a Migration, the new file system will 'cubby hole' all documents/files in a thing called 'legacy'.

Once a course files are in legacy, it's in legacy for ever.

Suggest migrating via git to 2.2.highest and stopping at that point to get courses devoid of legacy (involves backing up each course, start a new course with minimal config, then restoring the backup to the new course (the one you are in).  This will move the 'legacy' files into the new file system.  Once, having done that, one can resume the 'moodle march' upwards.  The reason for the stop ... 2.3, 2.4, and 2.5 can no longer use the 'work around' to get files out of legacy.

New courses will use the new file system with no legacy.

Also, work with a copy of your current 1.9 site ... DB, code, and data directory.  There is massive change to the data directory.

After each step up, do a complete site backup ... DB, code, data directory.  That becomes your fall back position just in case the next step up fails for some reason.

Easiest way to 'march' ... git:

Hi

my 2 cents

The VM is a _very_ good idea.

Starting with a fresh install just does not work. (or at least I could never get it to work)

Do the upgrade on the vm and then move it (backup restore it) to the live environment
