Replace old MAAS nodes that are deployed onto a Juju cloud
I have a situation where i have Openstack Charm Bundle Openstack base deployed onto a Juju Model backed by 4 physical MAAS nodes.
Now, there is a need to replace two of the MAAS nodes. These nodes now host critical Openstack services such as MySQL and Neutron-gateway.
Is it possible to deploy two new nodes into MAAS and the Juju model and migrate the openstack services from the old nodes two the new nodes, whilst not losing any data?
Would it be better to just take a clean start approach and deploy the openstack bundle all over again?
The bundle that is deployed onto juju is:
https://jujucharms.com/u/openstack-charmers-next/openstack-base-xenial-ocata/
Juju version: 2.3.7-xenial-amd64
