Vérification préalable à la mise à jour
From Joomla! Documentation
Le composant de vérification des mises à jour est la nouveauté de Joomla 3.10.x. Ce composant affiche les spécifications techniques du serveur sur lequel le site est installé, ainsi que le noyau et les extensions tierces qui utilisent le serveur de mise à jour sous forme de liste.
Spécifications techniques
La partie supérieure de la vérification de la mise à jour indique si votre environnement de serveur actuel est compatible avec Joomla 4.x pour les paramètres PHP et de base de données requis. Les données de la page Spécifications techniques seront mises à jour pour afficher les spécifications de Joomla 4.x lorsque nous serons plus proches de GA.
L'important est de vérifier si quelque chose est rouge et n'est pas compatible avec Joomla 4.x. Si ce n'est pas le cas, vous devrez en parler à votre hébergeur ou changer d'hébergement avant de migrer vers Joomla 4.x. Pendant une migration, c'est le moment idéal pour changer d'hôte. Voir le Migration Funnel pour plus d'informations sur la planification et les instructions étape par étape.
Vérification préalable des extensions
La partie extension du composant de vérification des mises à jour extrait des extensions tierces.
La liste est divisée en sections basées sur la balise targetplatform, les extensions que vous utilisez ou non. Pour les développeurs, voir Déployer un serveur de mise à jour pour plus d'informations sur ces balises et sur la manière de déployer un serveur de mise à jour. Pour plus d'informations sur le système de mise à jour Joomla, voir les pages Pré-requis pour la mise à jour du système Joomla ! et Extensions Gestion des mises à jour d'extensions.
En cliquant sur le lien Plus de détails à droite dans chaque en-tête de couleur, vous pouvez voir des informations supplémentaires sur les extensions installées sur votre site.
Mise à jour des informations non disponibles
Les extensions listées ici ne supportent pas encore le système de mise à jour Joomla ou au moins n'ont pas de balise targetplatform. (voir Deploying an Update Server) Veuillez contacter le développeur des extensions listées pour vous assurer qu'elles sont compatibles avec 4.x
The extensions listed here require an update to work correctly on 4.x. Please contact the developer of the listed extensions to make sure whether you have to update the component before or after the upgrade.
The extensions listed here claim to be 4.x compatible and no update is required.
Questions and Answers
Let's break this down into some questions and answers.
Q: What do the tags mean?
A: The green No Update Required tag means that the extension has been tagged by the developer that the extension as ready for Joomla 4. It should migrate with the one-click from 3.10.x to 4.x. Verifying with the developer is suggested.
The red Update Information Unavailable tag means that the extension has not added compatiblitly informatuion the extension. Check with the developer on the migration path from 3.10.x to 4.x.
The yellow/orange Yes (x.x.x) tag means that the extension has been tagged by the developer that the extension may need an update in order to be compatible with Joomla 4. Update the extension and see if it turns to a green Yes. If it doesn't, check with the developer on the migration path from 3.10.x to 4.x.
The gray Missing Compatibility Tag means that the extension doesn't have a tag or does not use the Update Server. The developer hasn't said yes or no or needs an update. In some cases, a package may have been installed and the component portion has a tag but the additional plugins or modules are missing tags. As always, you'll need to check with each extension developer to verify the migration path from 3.10.x to 4.x.
Q: What about the Joomla core components?
A: Joomla core extensions will migrate from 3.10.x to 4.x on the one-click with these exceptions:
The language packs are not yet ready for Joomla 4 (as of September 2020). Over time, they will be. If your site depends on other language packs, wait to migrate until all the language packs are ready.
The Weblinks component is not yet ready for Joomla 4 (as of September 2020). If you're going to continue using Weblinks in your Joomla 4 site, wait to migrate until the Weblinks component is ready.
Q: What about templates?
A: Because of the changes in Joomla 4, your template may or may not be compatible with Joomla 4. The core templates like Protostar, Beez3, Beez5, and so on will convert to the new Cassiopeia template on the one click and the older templates will be completely removed. If you're using a club template from a third-party developer that is not compatible with Joomla 4, you'll need to change your default template to Protostar (or Beez3) before you do the one-click. If you have older administrator templates or core templates, it's recommended to uninstall all of them except whichever of the core templates you will set as default. This includes Bluestork, Hathor, the other beez templates. You will keep Isis as the administrator template. You will keep either your compatible third-party template, Protostar or Beez3 as default. You will uninstall the rest.
Q: Can I uninstall plg_content_geshi?
A: Yes. This is leftover from the 2.5 life cycle and must be uninstalled.
Q: What about all that FOF, fef, etc.?
A: Many extensions in the red or yellow/orange headings will/may make it through the one-click and migrate fine. It is recommended that you go to Extensions→Manage→Manage and check all extensions. Typically the ones authored by Joomla will migrate on the one click. Typically the Akeeba extensions will too. Again, check with extension developers to verify the migration path on all third-party extensions.
Q: Does the Extensions Pre-Update Check show all the extensions installed on my site?
A: The Pre-Update Check will show all extensions. Only extensions that use the Update Server are given compatibility information. Those extensions that do not use the Update Server will show in the list with the Missing Compatibility Tag.
Summary
From a migration perspective, it is my belief that the Pre-Update Check should be used a guide. You'll want to have a second tab open with Extensions→Manage→Manage open in order to uninstall any extensions or check who they're authored by so you can contact third-party extension developers on the migration path they've established to migrate their extensions.
