How to upgrade AWS EC2 from t2.2xlarge to t3.2xlarge? - amazon-web-services

Question

I have an t2.2xlarge AWS EC2 instance that i need to change it's type to t3.2xlarge.
But when i try to start it i get an
"Error starting instances The requested configuration is currently not
supported. Please check the documentation for supported
configurations."
When i run the check script everything is fine
https://github.com/awslabs/aws-support-tools/tree/master/EC2/NitroInstanceChecks
OK NVMe Module is installed and available on your instance
OK ENA Module with version is installed and available on your instance
OK fstab file looks fine and does not contain any device names.
And i also did all the checks described here
https://aws.amazon.com/premiumsupport/knowledge-center/boot-error-linux-nitro-instance/
aws ec2 describe-instances --instance-ids my-instance-id --query "Reservations[].Instances[].EnaSupport"
[
true
]
Is there anything else i should change to be able to start it as t3.2xlarge?
To reproduce:
Create an t2.2xlarge instance with default settings
Stop it and change type to t3.2xlarge
Try to start it

Answer 1

I tried to launch a t3.2xlarge in us-east-1e and got the following error:
Your requested instance type (t3.2xlarge) is not supported in your requested Availability Zone (us-east-1e). Please retry your request by not specifying an Availability Zone or choosing us-east-1a, us-east-1b, us-east-1c, us-east-1d, us-east-1f.
AWS probably doesn't have t3.2xlarge instances available in this AZ.
