| ==Before upgrading please... ==
| |
| * Check your site 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
| |
| * Read [[Upgrading to Moodle 1.9]] if you are upgrading to 2.0 from 1.8 or 1.7
| |
| * Read [[Upgrading to Moodle 1.8]] if you are upgrading from 1.7
| |
| | |
| ==Upgrading more than one version==
| |
| | |
| In general, it is recommended to upgrade via each version of Moodle, for example 1.8 -> 1.9 -> 2.0. An exception to this is when upgrading from 1.5 or 1.6, when it is recommended that 1.7 be skipped, in other words upgrade 1.5 -> 1.6 -> 1.8 -> 1.9 -> 2.0. (The main reason for this recommendation is that the default roles settings obtained when upgrading to 1.7 are not ideal for 1.8 onwards.)
| |
| | |
| ==Now upgrade==
| |
| | |
| Once you have satisfied the requirements for Moodle 2.0, follow the instructions on the [[Upgrading|upgrading]] page.
| |
| | |
| Note, if you get a strange error about 'handling of PHP float numbers', please see [[Installation_FAQ#Moodle_claims_PHP_float_handling_is_not_compatible|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]].
