This module is designed to associate group specific block content with a group when using the Group module.
Requirements
- Group module (https://drupal.org/project/group) 1.2 or higher.
Migration
There is no easy way to migrate from https://www.drupal.org/project/group/issues/3014720 to this module as everyone's group content IDs will be different but the following code will hopefully point you in the right direction.
