title: In Azure Cosmos DB, can we change partition key later on once we decided at the beginning
body: <p>I am new to Cosmos DB and I noticed that we can set the partition key based on needs to scale effectively through code like this:</p>
  
  <pre><code>DocumentCollection myCollection = new DocumentCollection();
  myCollection.Id = "coll";
  myCollection.PartitionKey.Paths.Add("/deviceId");
  </code></pre>
  
  <p>Question is can we change the partition key later on after we created the collection and specified the partition key? As I may find out that the choice of partition key is not proper later.</p>
