I want to take the master DB instance offline

Verification: how do I know my system is in this situation?

• You should only be in this situation if you need to perform an action that requires disconnecting the current master DB from the Manager for MySQL set of instances.
• Common situations are master instance reboot, master instance re-configuration or simply termination of master instance.
  

Required actions: What recipes should I apply to solve the situation?

1. Promote slave DB to master DB
2. Launch a brand new slave template
3. Initialize slave DB from master DB (on the new instance)
4. Decommission old master safely. (i.e., the old master is "disconnected" from Manager for MySQL, and you can do whatever you want with it)
