Upgrading FAQ
How do I upgrade from 1.9.x to 4.3?[править]
1.x -> 1.9.19+ -> 2.2.11 -> 2.7.20 -> 3.2.9 on PHP7.1 -> 3.5 on PHP7.1/7.2 -> 4.3
(It is better to upgrade to latest current stable before going to next branch, the same for plugins; upgrading from early stable branches usually works but there is no guarantee.)
Moodle 2.2.11 may be downloaded from https://download.moodle.org/stable22/.
How do I upgrade Moodle? Do I just overwrite the files?[править]
Do NOT overwrite files, as it may cause strange errors. Read the Upgrading documentation before proceeding.
I obtain the message "Upgrade already running in this session, please wait!"[править]
Most likely you refreshed the page before the completion message. If you are absolutely sure that there are no upgrade processes active (php and/or mysql), you can click on "!!!" and restart the upgrade.
- Note: If you click on "'!!!" or try to restart the upgrade from another browser, there is a chance that your data in the database could be corrupted. If this happens, you will need to restore the database from sql dump and then restart the upgrade and wait - the process can take several hours on large sites.
Can I upgrade more than one version at a time?[править]
You can only upgrade to Moodle 4.4 from Moodle 4.1.2 or later. If upgrading from earlier versions, you must upgrade to 4.1.2 as a first step.
