I have create a cloudformation template that creates one SNS::Topic and bunch of other resources. Problem now is that when i try to update the stack, it fails with the following error

```
"Update to resource type AWS::SNS::Topic is not supported"

```

Stack Policy is:

```
{
  "Statement" : [
    {
      "Effect" : "Deny",
      "Action" : "Update:*",
      "Principal": "*",
      "Resource" : "*",
      "Condition" : {
        "StringEquals" : {
          "ResourceType" : ["AWS::SNS::Topic", "AWS::EC2::Subnet"]
        }
      }
    },
    {
      "Effect" : "Allow",
      "Action" : "Update:*",
      "Principal": "*",
      "Resource" : "*"
    }
  ]
}

```

CF Template is 

```
{
  "AWSTemplateFormatVersion": "2010-09-09",
  "Description": "......",
  "Resources": {
    "MySNSTopic":{
      "Type":"AWS::SNS::Topic",
      "Properties":{
        "DisplayName": "",
        "Subscription": [ ],
        "TopicName": { "Fn::Join": [ "-", [ "Simple", "sns", "topic" ] ] }
      }
    }
  }

```

Is there anything (even hackable) that i can change to let aws complete the aws update stack without deleting/modifying sns\_topic?
