Error: moodle error code cannotdowngrade

The error message “Cannot downgrade data from version X.Y.Z” implies that we are attempting to downgrade the Moodle installation to a prior version.

In this case the procedure is not feasible owing to incompatible data. Or database schema changes between the current and previous versions.

Moodle has a versioning mechanism for managing database schema changes and data structures. When we upgrade Moodle to a newer version, the database structure and data will change to meet the new version’s needs.

However, after the upgrading process is complete and updating the database, it is impossible to roll back to an earlier version. This is becasue the data may no longer be compatible.

Attempting to downgrade Moodle after an upgrade might result in data errors, data loss, or system instability.

Moodle’s architecture supports Upgrades, while it won’t support downgrades.

If we get the “Cannot downgrade data” error, it means that the database structure or data has changed in a way that makes the previous version we’re trying to install incompatible.

The version number (X.Y.Z) from which the system is unable to downgrade is often included in the error message.

Error: moodle error code cannotdowngrade: Resolve

To solve this error follow the steps given below:

• Restore a backup:

  We can revert to the old version if we have a backup of the Moodle instance from before the update. This will allow us to restore the system to its pre-upgrade state.
• Reinstall the previous version:

  Rather of downgrading the current installation, we can construct a fresh installation of the previous Moodle version and restore the course data or other required components from a backup.

  This will necessitate the installation of a second Moodle instance.
