Upgrading: Drupal 7 modules that have been removed from core

During the Upgrade process from Drupal 7 to Backdrop CMS, modules that were removed from Backdrop Core will effectively be disabled.

Disabling a module but not uninstalling it will leave it's data behind. Though lingering data is generally still a safe thing for Drupal or Backdrop sites, it is a best practice to completely uninstall modules that will never be used again, so that the data that module provides can be removed.

Below you'll find a list of Drupal 7 modules that have been removed from Backdrop core, along with additional information about what would be removed when the module is uninstalled.

Note: Please make a backup of the Drupal 7 site before attempting any of the clean-up tasks recommended below, many of them are destructive.
