Merge Risk: 🟡 Moderate · up to Resolve namespace-selection consistency and API-version-specific capability validation before merging: affected migrations can leave source workloads scaled down or relocate resources outside the controller-selected namespace. Tighten the cleanup assertion so API failures cannot hide remaining source Deployments. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The mode is explicitly enabled and retains important collision, identity and recovery safeguards. However, the compatibility check is not tied to the API version being written, and migration’s namespace choice is not checked against the controller’s eventual choice. These gaps can undermine the operator handover under incompatible schemas or changing bundle metadata. Production controller behavior and permissions were not fully established. Retained concerns

approvals also pin the selected bundle using info.Version, rather than leaving
version unconstrained; preserve the existing channel constraint and

When the metadata-derived target namespace does not exist, PrepareInstallNamespace creates it after info.CollectedObjects has been populated. The ns itself is therefore absent from the imported COS and has no COS ownerref

That might be on purpose, but I'll double-check.

You were right: the Namespace was missing from the imported COS. The focused fixture test exposed a collision when the catalog COS tried to take over the unowned Namespace. Commit d357557 includes the prepared Namespace in the migration COS from both the library and CLI paths, and the E2E test now verifies that the catalog COS owns it after handoff. The focused E2E passes.

- Line 268: Update the version loop containing the schema check to inspect only
the served schema whose version matches ocv1.GroupVersion.Version, regardless of
the order of versions in the CRD. Add mixed-version fixtures with both version
orders to verify the check consistently uses that schema.
Review comments at @test/e2e/migration/e2e_test.go:
- Around line 643-645: Update the source Deployment check in the migration test
to distinguish absence from lookup failures: call `kubectl get` with
`--ignore-not-found -o name`, fail the test if the command returns an error, and
fail if the trimmed output is nonempty. Keep the existing failure message
context for a Deployment that remains.

Include the prepared Namespace in migration COS revisions from both the library and CLI so the catalog revision can adopt it without collision. Check the served v1 ClusterExtension schema, tighten source-resource E2E lookup errors, and assert Namespace ownership after handoff. Signed-off-by: Todd Short <tshort@redhat.com>

Summary
Adds the explicit
--system-managed-install-namespacemigration mode for operator-controller v1.12.0's experimental optional-namespace API.ClusterExtension.spec.namespacewhile retaining the existing source-namespace default when the flag is absent.spec.namespace, before mutating OLMv0 resources.Validation
make migration/test-unitgo test ./... -count=1make migration/test-e2e-system-managed-namespacemake verifySummary by CodeRabbit
--system-managed-install-namespaceoption for single-operator migrations. It lets the controller choose the installation namespace using bundle metadata, while migration prepares that namespace and moves the operator’s resources there.
