Lightsail: CreateInstancesFromSnapshot Error

0

Hello, I have a tiny Debian instance on Lightsail I've been using for a few years. I'm trying to switch from dual stack to IPv6, so I created a snapshot and tried to create a new instance from that (as explained here), but I get the error "Error - CreateInstancesFromSnapshot[eu-central-1] - This bundle size isn't compatible with the selected blueprint debian_9_5. Choose a different bundle."

The instance has:

  • 512 MB RAM,
  • 1 vCPU,
  • 20 GB SSD

The only difference with the bundle I'm trying to buy is that the new bundle has 2 vCPUs instead of 1. I don't know if it's related, but the first time I tried to create the instance from the snapshot, I got an error because I was using a version of Debian that was too old. I have done a full-upgrade, created a new snapshot, and the error changed to "This bundle size isn't compatible with the selected blueprint".

Any help is appreciated

Hi,

An instance-snapshot of an instance created of some inactive and old blueprints such as debian_9_5 cannot be used to create an instance using the newer IPv6 bundles. If you would like to migrate to an IPv6 bundle, you will need to create a fresh new instance using one of the currently active Debian blueprints and an IPv6 bundle and then migrate your data and application from the old instance over to the new one.

One easy way to copy data/app over would be to create a disk-snapshot of the root volume (or system disk) of your old instance and create a disk from this snapshot. Then attach this disk to your other fresh new instance as a secondary disk and copy the data over.

Please refer this doc for detailed steps - https://docs.aws.amazon.com/lightsail/latest/userguide/amazon-lightsail-create-an-instance-root-volume-snapshot.html

After data has been copied, you could detach and delete the disk.

Thanks.

    I figured I'd have to recreate the instance from scratch, but I appreciate the disk-snapshot solution. By now I realized that I actually need IPv4 since my ISP doesn't support IPv6, so I'll wait for Ubuntu 24.04 LTS instances to become available and I'll recreate it from scratch. Thank you for the answer

    Sorry to hear IPv6 being unsupported by your ISP like many others :( Happy to help always!
