Database storage of configurations

IMPORTANT: Once you turn on database storage, you cannot use Continuous delivery. You can only get back to FileSystem storage mode by migrating the configurations back. For more information, see Migrate configurations.

Sitefinity CMS configurations are stored in .config files. By default, these files are located in folder ~/App_Data/Sitefinity/Configuration/. You can store the configurations of different servers in the database. This way, all servers will use the same configurations. 

NOTE: When you add or delete a language on your site, the changes are persisted on the file system, regardless the storage mode that you have configured. The changes are saved in the ResourceConfig file.
This is because languages are part of the building of the metadata source for connecting to the database. In addition, changing the languages changes the database structure and all structural changes are transferred through the deployment package 

To turn on database storage for configuration files, perform the following:

1. Open you web.config file.
2. Perform the following transformations:
3. Perform procedure Administration: Move the database connection string in the web.config file.
4. Save and close the web.config and restart the application.
   The storage of configuration files is moved to the database. The existing configurations are taken as default. The files in ~/App_Data/Sitefinity/Configuration folder are made read-only and any future changes to the .config files are written to the database where each server can access them.

IMPORTANT: You must not remove existing configuration files from the project's ~/App_Data/Sitefinity/Configuration folder, because Sitefinity CMS continues to use them to read the default values. Only new changes are written to the database.
