migrator-awx.yml

## This modified version of the playbook expects a variable "source_vm_name" to be
## provided. In turn, it will fetch info on that VM, and the host it currently
## resides on, to dynamically populate the inventory groups. Although this was
## intended for use in self-service migrations in AWX, it could also be useful to
## further simplify the migration process when running manually.
