Automation considerations


This task also did not require any new framework decisions. All the other automation decisions we reviewed previously carried over.

Before we start, it is worth noting that when automating a task such as this one (migrating an instance and disabling compute nodes) it is best to collect details concerning them both before and after the migration. Having those details will simplify the process of reversing your changes, if required. Yes, this will add additional tasks to your role making it slightly more complex but still well worth it.

With this said, we are now ready to proceed with creating our next playbook and role.
