title: Does importing an AWS RDS Aurora 5.7 work in v0.11.7?
body: <p>I'm upgrading an Aurora RDS from Aurora 1.x (MySQL 5.6) to Aurora 2.x (MySQL 5.7). I've already done it in AWS (manually through a snapshot, as it is still not supported by a simple click), and I'm trying to <strong><em>state rm</em></strong> and <strong><em>import</em></strong> it into Terraform (I've already upgrade the code in Terraform), it succeeds, but then <strong><em>terraform plan</em></strong> wants to destroy and recreate the cluster (and therefore the instance too) for this reasons:</p>
  
  <pre><code>availability_zones.#:          "3" =&gt; "2" (forces new resource)
  availability_zones.1924028850: "eu-west-1b" =&gt; "eu-west-1b"
  availability_zones.3953592328: "eu-west-1a" =&gt; "eu-west-1a"
  availability_zones.94988580:   "eu-west-1c" =&gt; "" (forces new resource)
  [...]
  engine:                        "aurora-mysql" =&gt; "aurora" (forces new resource)
  [...]
  </code></pre>
  
  <p>The changes I did in TF were, for the RDS cluster:</p>
  
  <pre><code>-  engine         = "aurora"
  -  engine_version = "5.6.10a"
  +  engine         = "aurora-mysql"
  +  engine_version = "5.7.12"
  </code></pre>
  
  <p>And for the parameter groups (both cluster and instance):</p>
  
  <pre><code>-  family      = "aurora5.6"
  +  family      = "aurora-mysql5.7"
  </code></pre>
  
  <p>The parameter groups are imported OK.</p>
  
  <p>I suspect the problem may be because it tries to change the correct <strong>engine</strong> "<strong>aurora-mysql</strong>" for the wrong one "<strong>aurora</strong>", but why?! It's imported Ok and it's also OK in my Terraform code. Is that a TF bug? I can't find anything.</p>
  
  <p>I'm using <strong>Terraform v0.11.7</strong></p>
  
  <p>From the doc:</p>
  
  <blockquote>
    <p>The engine name for Aurora MySQL 2.x is aurora-mysql; the engine
    name for Aurora MySQL 1.x continues to be aurora.   The engine version
    for Aurora MySQL 2.x is 5.7.12; the engine version for Aurora MySQL
    1.x continues to be 5.6.10a.   The default parameter group for Aurora MySQL 2.x is default.aurora-mysql5.7; the default parameter group for
    Aurora MySQL 1.x continues to be default.aurora5.6.   The DB cluster
    parameter group family name for Aurora MySQL 2.x is aurora-mysql5.7;
    the DB cluster parameter group family name for Aurora MySQL 1.x
    continues to be aurora5.6.</p>
