Configuration Update Manager project
The Configuration Update Manager project consists of two modules:
Configuration Update Base: A base module providing functionality related to updating and computing differences between configuration versions. No user interface; used by other modules such as Features.
Configuration Update Reports (in the config_ui sub-directory of this project): Adds an updates report and revert functionality to configuration management. Depends on Configuration Update Base.

This module provides a report that allows you to see the differences between the default configuration items provided by the current versions of your installed modules, themes, and install profile, and the active configuration of your site. From this report, you can also import new configuration provided by updates, and revert your site configuration to the provided values.
The main use case is: You update a module, and it has either changed default the configuration that it provides or added new default configuration items that you didn't get when you first installed the module. You want to be able to import the new items, view the differences between the active site configuration and the changed configuration, and possibly "revert" (or it may be an update) to the newly-provided default configuration.
Install the module in the normal way for Drupal modules. The only dependencies are the Configuration Manager module (Drupal core), and the Configuration Update Base module (part of this same project download).
GENERATING REPORTS IN THE USER INTERFACE
You can generate configuration reports at Administration >> Configuration >>
Development >> Configuration management >> Update report (path:
You can generate a report for a particular type of configuration object, such as
Actions, Tours, Views, etc. Or, you can generate a report for an installed
module, theme, or install profile. Finally, you can generate a report that
contains all configuration in one report.
The report has three sections, depending on what type you choose:
1. Missing configuration items: Configuration items that are provided as
defaults by your currently-installed modules, themes, and install profile
that are missing from your active site configuration.
Any items listed here can be imported into your site.
2. Added configuration items: Configuration items that you added to the site
(not provided by a currently-installed module, theme, or install
profile). This section is only shown when you are running the report based on a
Items listed here can be exported, which is useful for developers or if you want
to keep your site configuration in a version control system.
3. Changed configuration items: Configuration items that are in your active site
the configuration that differs from the same item currently being provided by an
installed module, theme, or install profile.
You can export these items, see the differences between what is on your site
and what the module/theme/profile is currently providing, or "revert" to the
version currently being provided by the module/theme/profile in its default
Note that the differences may be a bit hard to read, but hopefully, they'll
give you the general idea of what has changed.
GENERATING REPORTS USING DRUSH COMMANDS
The reports detailed in the previous section can also be generated, in pieces using Drush commands (https://drupal.org/project/drush):
drush config-list-types (clt)
Lists all the config types on your system. Reports can be run for
'system.simple' (simple configuration), and 'system.all' (all types), in addition
to the types listed by this command.
drush config-added-report (cra) drush config-missing-report (crm) drush config-different-report (crd)
Run config reports (see below).
drush config-diff (cfd)
Show config differences for one item between active and imported (see below).
The report commands run reports that tell what config has been added, is
missing, or is different between your active site configuration and the imported
default configuration from config/install directories of your installed profile,
modules, and themes.
For each report except "added", the first argument is one of:
- type: Runs the report for a configuration type; use drush config-list-types to
- module: Runs the report for an installed module.
- theme: Runs the report for an installed theme.
- profile: Runs the report for the install profile.
The second argument for reports is the machine name of the configuration type,
module, theme, or install profile you want to run the report for. For the
"added" report, this is the only argument, as the added report is always by
These are the same as the reports you get in the UI, which is described above;
the only difference is that in Drush the report is separated into pieces.
Once you have found a configuration item with differences, you can view the
differences using the config-diff command. This is a normalized/formatted diff
like in the UI of this module, so see above for details.
drush clt drush crm module node drush cra block drush crd theme Bartik drush crd type system.all drush crd type system.simple drush crd profile standard drush cfd block.block.bartik_search
Once you have figured out which configuration items are added, missing, or
different, you can:
- Export them - see drush config-export.
- Import missing configuration or revert to provided default values. To do this:
(1) Locate the configuration file in the install profile, module, or theme
(2) Copy this file to your configuration staging directory.
(3) Run drush config-import. You might want to use the --preview option to see
what differences you are about to import, before running the import, or
use the drush config-diff command to look at individual differences.
Here are some notes about how this module functions:
* This module is always looking at the base configuration items, without
overrides (from settings.php, for example) or translations.
* It is possible for an install profile on a site to provide configuration that
overrides configuration from a module or theme. The install profile version always
takes precedence. As an example, consider the case where module Foo
provides a configuration item called foo.settings, and install profile Bar overrides
this with its own file. Any reports that include foo.settings will
be based on the differences between your site's active configuration and the version
in the install profile. This is not usually a problem, but it can be
confusing if you're looking at the Foo module report. The foo.settings item will
be present, but the differences reported will be between the install
profile's version and your site's active configuration, not the differences between
the Foo module version and your site's active configuration.
