I want to change the instance type "windows with sql server" to "windows standard" for my EC2

Hello.

To change your EC2 instance type from "Windows with SQL Server" to "Windows Standard" without SQL Server, follow these steps bellow.

1. Create a Backup (AMI) of Your Existing Instance

• In the AWS Management Console, go to EC2 > Instances.
• Select your current EC2 instance (m6i.2xlarge with SQL Server).
• Choose Actions > Image and templates > Create image to create an AMI as a backup.

2. Launch a New EC2 Instance with Windows Standard

• Navigate to EC2 > Instances > Launch instances.
• Choose Microsoft Windows Server (without SQL Server) from the available options.
• Select the same instance type, m6i.2xlarge.
• Use the same settings (VPC, subnet, security groups) as your current instance.

3. Detach and Attach EBS Volumes

• After launching the new Windows instance, stop both the current and new instances.
• In the EC2 console, go to Volumes and locate the EBS root volume of your current instance.
• Detach this volume and then attach it to the new instance (make sure it's attached as the root volume, /dev/sda1).

4. Verify and Restart

• Start the new instance.
• Check that the new instance boots correctly and all your data and applications are intact (minus the SQL Server).

5. Terminate the Old Instance

• Once you've confirmed the new instance is functioning correctly, you can terminate the old instance with SQL Server to avoid additional costs.
