It is highly recommended that upgrades from an earlier version (especially from version 4.8!) are done local (or one a second installation) and not on the production system, as many fixes and changes might came along with the upgrade depending on the amount of modules and plugins used in the system.

Doing an update on a local or second system has the major advantage that your productive page is only a few minutes not reachable and you can take as long as you want doing the upgrade. Especially on upgrade from version 4.8 this is very useful, as fixing all old functionality may take some time. However, as an update can take a long time, you must ensure, that no new content is being added to the page once you have taken a backup of all files and the database. Otherwise, the replace of your local installation also would replace any content entered in the meantime. To shorten the maintenance time of the page you could take another backup of database and files on the day, you are performing the upgrade of productive system. Take care, that you are doing all steps according to the guide, to prevent any mistakes. |

Upgrading to another version of CONTENIDO can change the systems behaviour. Thus, modules and plugins must be checked. Please have a look for compatibility of all plugins you are using. Especially on upgrades from version 4.8 the author of the plugin must offer a version that works with version 4.9. Plugins of version 4.8 definitely do NOT work with version 4.9 because the plugin system was changed. Chains should work as before.On upgrade from version 4.8 to 4.9 check all languages of all clients if they have a configured language and country code. The upgrade process will not proceed if it detects any language without a country and/or language code. Set these codes in the language administration of CONTENIDO by selecting a value for "Country" and "Language".
Create a backup of filesystem and database

When you encountered any problems during update, please have a look into our support forum on forum.contenido.org. Maybe other persons did have the same problem and you can find a solution for this problem there.
...
When you upgrade from version 4.8 you must move the configuration files stored in the root directory of your client to the folder data/config/ENVIRONMENT. Do not miss other local configuration files such as config.local.php and config.after.php!
If you had changed configurations for the backend, you must apply them to the new configuration files in data/config/ENVIRONMENT. We recommend you to use the config.local.php, so you must not modify any core files.
Fixing usage of removed functionality
Every time an update removes deprecated functionality (such as an upgrade from version 4.8) you must check your modules and plugins for outdated functionality. If you do not, backend and frontend will behave uncorrectly.
If the version you are upgrading to has any removed outdated functionality you can check in the Changelog area. For upgrade from version 4.8 please have a look at this page.Please keep in mind, that plugins have other structure in version 4.9 and may not work immediately after update. It belongs to the plugin author If you have some problems with plugins, please contact the plugin authors to advise you what to do on upgrading the system.
