+ * This migration will set the columns of the oer campus to the correct state
+ * regarding the collations of some columns. This should only be necessary if
+ * the plugin "Lernmarktplatz" was installed before the migration of Stud.IP
+ * that introduced the oer campus. In any other case the tables should not be
+ * changed since they are already in the correct format.
