Backup and restore questions
Is it possible to restore "openstack" to a different cloud? For example, either of the following; 1. Backup Openstack with version "X" and restore to different fresh deployment of the same version or 2. Backup Openstack with version "X" and restore to Openstack Version Y or even later, Z And are there any tools associated with Openstack that achieves this? I think this would come under the term "migration". I've been reading the Openstack docs with regards to backup/restore and doing some trial and error on my side. It appears to me that the "backup/restore" is only applicable for the same system - can anyone confirm it? Are there any options for transferring data to a different Openstack deployment?

Yes, this is definitely possible. I know some users of Kolla-Ansible migrated their manual and other-deployment-tool-deployed OpenStack-based clouds to use Kolla-Ansible. This is certainly possible using the same version of services. All the data is captured in the sql database (usually mysql). Apart from custom config, this is the most important part to keep backed up (and obviously your users' data in store :-) ). Please read the following great (opinion mine) blog post by Pierre Riteau from StackHPC, that nicely summarizes steps required for such migration: https://www.stackhpc.com/migrating-to-kolla.html -yoctozepto
