Upgrading to Moodle 2.0
From MoodleDocs
Template:Moodle 2.0When upgrading to Moodle 2.0, you must have Moodle 1.9 or later. if you are using an earlier version of Moodle (eg 1.8.x) then you need to upgrade to Moodle 1.9.x first.
We advise that you test the upgrade first on a COPY of your production site, to make sure it works as you expect.
Before upgrading please...
- Always check your site to make sure it meets all system requirements for 2.0 in Administration > Server > Environment
- Do a full database backup!
- Remember to purge PHP cache if using any PHP accelerator
Now upgrade
Once you have satisfied the requirements for Moodle 2.0, follow the instructions on the upgrading page.
Note, if you get a strange error about 'handling of PHP float numbers', please see this FAQ entry.
Verify the upgrade (optional)
If you wish to confirm that the database definitions in the upgraded database match the definitions of a new, clean install (which they should) you might like to look at Verify Database Schema.
