+Upgrade Steps
+-------------
+
+Each service template may optionally define a `upgrade_tasks` key, which is a
+list of ansible tasks to be performed during the upgrade process.
+
+Similar to the step_config, we allow a series of steps for the per-service
+upgrade sequence, defined as ansible tasks with a tag e.g "step1" for the first
+step, "step2" for the second, etc.
+
+ Steps/tages correlate to the following:
+
+ 1) Quiesce the control-plane, e.g disable LoadBalancer, stop pacemaker cluster
+
+ 2) Stop all control-plane services, ready for upgrade
+
+ 3) Perform a package update, (either specific packages or the whole system)
+
+ 4) Start services needed for migration tasks (e.g DB)
+
+ 5) Perform any migration tasks, e.g DB sync commands
+
+ 6) Start control-plane services
+
+ 7) Any additional online migration tasks (e.g data migrations)
