A company has a large number of `CustomResourceDefinition` (CRD) manifests using `apiextensions.k8s.io/v1beta1`. They are running Kubernetes v1.21 and plan to upgrade to v1.22. The team wants to minimize manual effort and avoid downtime. Which approach is the most efficient?

Keep the `v1beta1` CRDs and use a conversion webhook.

Upgrade to v1.22 first and then manually update the CRD manifests.

Use `kubectl convert` on each CRD manifest.

Write a script to convert all CRD manifests from `v1beta1` to `v1` and validate them with `kubectl apply --dry-run=client`.

A company is migrating all `Ingress` resources from `networking.k8s.io/v1beta1` to `networking.k8s.io/v1`. The cluster runs Kubernetes v1.22. During the migration, the team notices that the `pathType` field is now required. What is the best approach to handle this change?

Omit `pathType` and let the API server default it to `ImplementationSpecific`.

Keep the `v1beta1` version and use a conversion webhook.

Add `pathType: Prefix` or `pathType: Exact` to each path in the Ingress manifests.

Use `pathType: Wildcard` to match all paths.

A team is running Kubernetes v1.24 and is planning an upgrade to v1.25. They have several `PodSecurityPolicy` (PSP) resources defined using `policy/v1beta1`. What should the team do to prepare for the upgrade?

Keep the PSPs; they will continue to work in v1.25.

Migrate to Pod Security Admission (PSA) before upgrading, as PSP is removed in v1.25.

Change the apiVersion to `policy/v1` for the PSPs.

Use `kubectl convert` to update the PSPs to a new API version.

A team is running Kubernetes v1.21 and has a mix of manifests using `apiextensions.k8s.io/v1beta1` for CustomResourceDefinitions (CRDs). The team is planning an upgrade to v1.22 next quarter. What should the team do to ensure the CRDs continue to work after the upgrade?

Migrate all CRD manifests to `apiextensions.k8s.io/v1` before upgrading.

Keep the manifests as-is; the API server will automatically convert them.

Use `kubectl convert` on the CRD manifests after the upgrade.

Upgrade to v1.22 first, then check if `v1beta1` still works.
