In Rancher v2.6.4, the cluster-api module has been upgraded from v0.4.4 to v1.0.2 in which the apiVersion of CAPI CRDs are upgraded from `cluster.x-k8s.io/v1alpha4` to `cluster.x-k8s.io/v1beta1`. This has the effect of causing rollbacks from Rancher v2.6.4 to any previous version of Rancher v2.6.x to fail because the previous version the CRDs needed to roll back are no longer available in v1beta1.
To avoid this, the Rancher resource cleanup scripts should be run **before** the restore or rollback is attempted. Specifically, two scripts have been created to assist you: one to clean up the cluster (`cleanup.sh`), and one to check for any Rancher-related resources in the cluster (`verify.sh`). Details on the cleanup script can be found in the [rancher/rancher-cleanup repo](https://github.com/rancher/rancher-cleanup).
To avoid rollback failure, the following Rancher scripts should be run **before** you attempt a restore operation or rollback:
* `verify.sh`: Checks for any Rancher-related resources in the cluster.
* `cleanup.sh`: Cleans up the cluster.
See the [rancher/rancher-cleanup repo](https://github.com/rancher/rancher-cleanup) for more details and source code.
