   4 # file. E.g. Pacemaker cluster transitions for existing deployments,
   5 # matching changes to overcloud_controller_pacemaker.pp (Puppet
   6 # handles deployment, this file handles migrations).
   7 #
   8 # This file shouldn't execute any action on its own, all logic should
   9 # be wrapped into bash functions. Upgrade scripts will source this
  10 # file and call the functions defined in this file where appropriate.
  11 #
  12 # The migration functions should be idempotent. If the migration has
  13 # been already applied, it should be possible to call the function
  14 # again without damaging the deployment or failing the upgrade.
