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 new Slave-DB
  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)
