+	 * A group (group2) is optionally anti-colocated (at score -5000) with
+           another group (group1)
+	 * There are two nodes, and the groups are active on different ones
+	 * The dependent group's last member (member2b) is failed and has
+           reached its migration-threshold
+
+	 In this situation, the goal of keeping as many resources active as

+         dependent group should move to the primary group's node.
