+# Special pieces of upgrade migration logic go into this
+# file. E.g. Pacemaker cluster transitions for existing deployments,
+# matching changes to overcloud_controller_pacemaker.pp (Puppet
+# handles deployment, this file handles migrations).
+#
+# This file shouldn't execute any action on its own, all logic should
+# be wrapped into bash functions. Upgrade scripts will source this
+# file and call the functions defined in this file where appropriate.
+#
+# The migration functions should be idempotent. If the migration has
+# been already applied, it should be possible to call the function
+# again without damaging the deployment or failing the upgrade.
