How to upgrade a convertible RI instance?
1
I purchased a convertible RI r6a.32xlarge. What do I need to purchase or do to upgrade it to r6a.48xlarge? According to the documentation, I need to pay a normalization factor of 128 to equal the NF for the r6a.48xlarge (384). Do I just purchase the r6a.48xlarge instance and upgrade like that? Or r6a.16xlarge and then merge it with my instance? Documentation is uclear.

Here are the steps I would follow in order to meet your requirements to exchange your r6a.32xlarge to a r6a.48xlarge instance:
- Log into your AWS Account and navigate to the EC2 Console
- Under the Instances section on the left, choose Reserved Instances
- There you should have a list of reserved instance to choose from. Select the r6a.32xlarge of interest
- Open Actions and choose Exchange Reserved Instances. Since r6a.48xlarge is of a higher value than an r6a.32xlarge instance, you should be able to exchange it there
Here is some more documentation on the subject if you are interested in learning more: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ri-convertible-exchange.html

Do I have to stop my current r6a.32xlarge instance remove any mounts etc before I upgrade?
If you have already upgraded your instance itself, exchanging the convertible RI will not impact your instance as it is simply a pricing plan.
However, if you are talking about upgrading the EC2 instance itself, you will want to follow the instructions presented in this documentation: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-resize.html
The nature of your EC2 instance (EBS Compatible, EBS Non compatible, or Instance store) will determine the best steps for upgrading the size.
