If you've moved your AKS cluster to a different subscription or the cluster's subscription to a new tenant, the cluster won't function because of missing cluster identity permissions. AKS doesn't support moving clusters across subscriptions or tenants because of this constraint.

# Troubleshoot the Throttled error code (429)
11+
12+
This article discusses how to identify and resolve the `Throttled` error (status 429) that occurs when you try to create and deploy a Microsoft Azure Kubernetes Service (AKS) cluster.
13+
14+
## Symptoms
15+
16+
When you try to create an AKS cluster, you receive the following "The PutManagedClusterHandler.PUT request limit has been exceeded" error message that shows a "SubCode" value of **Throttled** and a "Status" value of **429**:
17+
18+
> Category: ClientError;
19+
>
20+
> SubCode: Throttled;
21+
>
22+
> OrginalError: autorest/azure: Service returned an error. **Status=429**
23+
>
24+
> **Code="Throttled"**
25+
>
26+
> Message="> The PutManagedClusterHandler.PUT request limit has been exceeded for SubID='*\<subscription-id-guid>*', please retry again in X seconds. For more information, please visit aka.ms/aks/throttling";
27+
Request throttling can occur on various Azure components, so the error message might be different depending on the type of resource where this issue occurs.
28+
29+
Resource provider throttling is independent of ARM throttling and is tailored to the operations of a specific resource provider. In this scenario, AKS resource provider throttling is specific to the AKS resource provider and applies only to operations related to AKS resources.
30+
31+
## Cause
32+
33+
AKS requests are throttled. For information about how AKS limits work and the specific limits per hour, see [Throttling limits on AKS resource provider APIs](/azure/aks/quotas-skus-regions#throttling-limits-on-aks-resource-provider-apis).
34+
35+
## Solution
36+
37+
To resolve this issue, examine and modify your access pattern of the throttled subscription. The following table lists the possible access patterns and corresponding solutions.
38+
39+
| Access pattern | Solution |
40+
| -------------- | -------- |
41+
| Automated scripts constantly run LIST operations against managedCluster resources. | Run the scripts less frequently. |
42+
| Users attempt to deploy multiple AKS clusters in a short period of time. | Space out deployments or use different subscriptions.|
43+
| Users attempt to modify the same AKS cluster multiple times consecutively. | Space out operations. Ensure successful completion before initiating another one.|
44+
| Users attempt to add, modify, or delete one or more agentPools on the same AKS cluster. | Space out operations. Ensure successful completion before initiating another one. |
