We've been using openstack-ansible since it existed, it's working well
for us.

It can be painful, but it's worked out in the long run.

Openstack-ansible, which is Openstack big-tent.  It used to be
os-ansible-deployment in stackforge, but we've removed the rackspacisms.
 I will say that openstack-ansible is one of the few that have been
doing upgrades reliably for a while, since at least Icehouse, maybe further.

Our team was somewhat bigger than most as we have many deployments and
we had to do it from scratch.  If you CAN do it solo, but I'd recommend
you have coverage / on call for whatever your requirements are.

For Openstack-ansible I'd recommend deploying a service at a time,
migrating piecemeal.  You can migrate to the same release as you are on
(I hope), though I'd recommend kilo or greater as upgrades can get
annoying after a while.
