Migrate From a Linux PV AMI to a Linux HVM AMI

(Strongly recommended) Copy data and move applications from the PV instance to a new HVM instance

2.    Copy data from the PV instance to the new HVM instance in one of the following ways:

  • Run Linux utilities such as rsync, scp, or drbd to securely copy data between the instances.
  • Copy the PV instance data to an EBS volume and detach the volume. Then, attach the volume to the new HVM instance.

3.    Install and configure your applications on the HVM AMI.

Convert the PV instance into an HVM instance

If copying data from the PV instance to a new HVM instance doesn’t suit your needs, you can convert a PV instance into an HVM instance by following these steps:

Note: These are general guidance steps. Be sure to modify the steps as needed for your configurations.

1.    Stop the PV instance.
Note: We recommend that you perform this step on a test PV instance. To create the test instance, first create an image of your PV instance. Then, launch a new PV instance

from the image.

2.    Create a snapshot of the PV instance’s root volume.

3.    Restore the PV instance's root volume snapshot as a new EBS volume. The volume must be restored in the same Availability Zone as the PV instance.

4.    Launch a new instance from an Amazon Linux HVM AMI. The instance must be launched in the same Availability Zone as the PV instance.

5.    Choose the EBS volume restored from the PV instance's root snapshot. Then, attach the volume to the new HVM instance as /dev/xvdf.

6.    Create a new, blank EBS volume that is the same size as the volume restored from the PV instance's root snapshot. Attach the new, blank EBS volume to the HVM instance as /dev/xvdg.
Note: After this step, your new HVM instance will have three volumes.

7.    Connect to your new HVM instance using SSH.
Note: You must have root-user privileges to proceed with the next steps.

8.    Run this command to display your volumes:
