I faced the same problem on my setup:
OS: Ubuntu 14.04 OpenStack: Kilo from the ubuntu-cloud repo
I could rename the availability-zone from the dashboard or the API but I couldn't migrate the instances anymore. I had to edit the following fields:
db->nova,table->instances,row->availability_zone db->neutron,table->ports,row->device_owner
after the manually update the VMs could be migrated again.
