What is a Fast Forward Upgrade?
A fast-forward upgrade is an offline upgrade which effectively runs the upgrade processes for all versions of openstack components from your originating version to your desired final version.
Preconditions
- Control plane will be down for the entire time of upgrade
- VMs should be accessible by customer
- Since control plane is down, operator can't do actions on existing instances (duh!)
- Take a full backup of your database before running the migration scripts just in case things get weird
