Migrate Gitlab container registry to another container registry

Hello there,

With the change coming up to the free tier, I would need to move my container registries to another provider (due to the new stockage prices).
Is there a way to export or migrate my images in Gitlab to another provider ?

For our projects, we have an image per branch, each branch is a different deployment in production; each image is pulled to a pod in our Kubernetes cluster.
If there is no way to export my images, I would need to rebuild all my different branches to push it to the new registry which can be a pain.

If anyone have an idea to migrate our registry or a “pain free” to rebuild all our images it would be awesome.
