Hello, I'd advise you to follow the standard OpenStack-Ansible path, which is upgrading from Mitaka to Newton, then do your ubuntu upgrade to xenial. From Newton onwards, we have code taking care of the rolling part of the upgrade, which should help you getting to Pike, after a series of upgrades (N->O->P) under ubuntu 16.04.
