 ### Access Management
   
-Introducing new cluster(s) creates complexity elsewhere. A tenant needs the ability to request
-access to a namespace from which they can manage select resources
-(e.g. `ClusterTemplateInstances`, `Secrets`, `ClusterPools`). `SpaceRequests`, which the
-user already has permission to create in their tenant namespace, can be leveraged here.
-A new cluster role will be created on the `ToolchainCluster` Custom Resource to classify the
-cluster(s) used for test environment provisioning. The `SpaceRequest` controller, noticing the
-cluster role on the request will create the namespace on the remote cluster. It will also create a
-secret in the tenant namespace containing a token for a service account with access to the remote
-namespace. This secret can then be used from any `PipelineRun` workload like any other.

+Should a new `NSTemplateTier` be created, existing tenants can be migrated to the new tier by an
+admin with a single `sandbox-cli` command. This technique can also be used for a manual approval
+workflow, if desired.
