<p>Is it possible to change the VPC of an already created EKS cluster? Or do I have to create a new one and there to select the new VPC?</p>

<p>you should be able to change the VPC configuration for the EKS cluster. However, as per the documentation which I found, it states that if VPC config is updated, the update type is replacement i.e., a new cluster will be created with the updated config.</p>

<p>Please see <a href="https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-eks-cluster.html#cfn-eks-cluster-resourcesvpcconfig" rel="noreferrer">https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-eks-cluster.html#cfn-eks-cluster-resourcesvpcconfig</a> for more information</p>

<p>Hope this helps. </p>
