Upgrading to Moodle 2.0
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.
System requirements
- PHP must be 5.2.8 or later
- Databases should be one of the following:
- MySQL 5.0.25 or later (InnoDB storage engine highly recommended)
- PostgreSQL 8.3 or later
- Oracle 10.2 or later
- MS SQL 2005 or later
- Any standards-supporting browser from the past few years, for example:
- Firefox 3 or later
- Safari 3 or later
- Google Chrome 4 or later
- Opera 9 or later
- MS Internet Explorer 7 or later (Even Google don't support IE6 any more)
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.
Moodle 2.0 supports running the upgrade from the command line, rather than through a web browser. This is likely to be more reliable, particularly for large sites.
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.
