Important versions for upgrade path
Open Y development moves quickly and in this document, we flag important versions that should not be skipped while you upgrade your sites.
Determining your upgrade path
For example: If you are on Open Y 8.1.2 and want to upgrade to Open Y 184.108.40.206 you should make it in a couple of steps
- Upgrade 8.1.2 to 220.127.116.11
- Upgrade 18.104.22.168 to 22.214.171.124
- Upgrade 126.96.36.199 to 188.8.131.52
- Upgrade 184.108.40.206 …
These supplemental documents elaborate on a few specific cases:
220.127.116.11- Optional, when you have a lot of customized code and 18.104.22.168 is failing in most places.
22.214.171.124- This is a very important step everyone should have. After this version,
drush entupstops working. In this version, we finally migrated to the core media subsystem, and before going further it is important to upgrade media by upgrading your site to this version first.
126.96.36.199- This is a very stable Drupal 8 based Open Y with a bunch of contrib module updates. This is one of the last Drupal 8 based Open Y versions before the upgrade to Drupal 9 core. Also, in 188.8.131.52 and 184.108.40.206 we started to introduce multiple version constraints in
composer.jsonto allow developers to choose between the minimum or latest dependency versions. This is for securing the upgrade path as well as adding flexibility for version selection if needed.
220.127.116.11- Drupal 9 version which must be used in the upgrade path before going to 18.104.22.168+. This version added 9.0-9.1 Drupal Core and disabled deprecated components.
22.214.171.124- Removed a bunch of unused modules from distribution.
If you are faced with an issue when
composer installs an improper version of
drupal/core for the chosen version of Open Y from the list above, please use this trick in order to downgrade:
composer require drupal/core-recommended:9.2.8
Run the above command where your
docroot is. Use the current core version instead of
