I think I understand how to manage system updates using tools like
snap, and others. I do NOT have any understanding about how to gracefully migrate an existing EC2 instance from one version of a VMI to another.
When I need to spawn more instances in the future, should be build them from this new VMI (from scratch)? I would rather snapshot the EC2 instance that I know works and then build a new EC2 instance from that snapshot.
Do I need to do anything in response to this email?
