Can't create instance from snapshot of old blue print in lightsail

Question

I have a snapshot created from a ubuntu 16.04 (OS is updated to Ubuntu 20.04 in snapshot). But when creating instance from snapshot. i got the error of  
This bundle size isn't compatible with the selected blueprint ubuntu_16_04_2. Choose a different bundle.
It seems that OS is determined by the plan I originally chose but not what snapshot is stored. What can I do?

Answer

Hi,

Are you perhaps trying to create the new instance with the IPv6-only bundles (i.e. the ones without a public IPv4 address) ?

An instance-snapshot of an instance created of some inactive and old blueprints 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 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.
