You can use the image replication function to convert an encrypted image to an unencrypted image, or the other way around. You may need to replicate an image in the following scenarios:
Encrypted images cannot be shared with other tenants or published as a Marketplace image. If you want to publish or share an encrypted image, you can replicate it to an unencrypted one.
Keys for encrypting the images cannot be changed. If you want to change the key of an encrypted image, you can replicate this image to a new one and encrypt the new image using an encryption key.
If you want to store an unencrypted image in an encrypted way, you can replicate this image as a new one and encrypt the new image using a key.
You can replicate private images in Normal or Normal (Uninitialized) state.
Full-ECS images cannot be replicated.
The image to be replicated is in Normal or Normal (Uninitialized) state.
If you want to encrypt the image or change a key, select KMS encryption and select the key to be used from the drop-down list.
