This assumes that you are already using Opigno 2.x (this does not cover upgrading from Opigno 1.x branch).

This also assumes that you initially installed Opigno using Composer. If you initially installed Opigno by downloading the tarball version, upgrade with Composer won't work.

If there are updates for Opigno LMS you can easily install them with Composer.

All Composer commands must be executed in the folder of your project at the same level as the folders web, drush etc.

First, you need to check if updates are available:
```
composer outdated opigno/opigno_lms
```
If 'version' and 'latest' are different that means updates are available.
Install updates:

NOTE: if you already installed some packages that are not part of Opigno LMS you should include them in a new composer.json file, otherwise Composer may remove them
```
// Clear composer cache
composer clearcache
// Check if updates will run without any issues
composer update --dry-run
// Run updates
composer update
```
During the update process some warnings may appear in relation with some modules (drupal/calendar, drupal/views_role_based_global_text), mentioning that they were modified, and asking "Discard changes?". The answer should be "y".
These modules will be updated to new versions.

Then update database and clear cache in admin interface or by Drush:
```
drush updatedb
drush cr
```

Typical problems:

If updates are available but can't be installed you can run this command to check the reasons why it can't be done:
```
composer prohibits opigno/opigno_lms
```
