  When POSTing xml for a profile originally created with an earlier version of Conductor Live , set content-type to application/vnd.elemental\+xml;version=n.n.n, where n.n.n is the number of the Conductor Live version used to create the profile. For example, if the profile was created with Conductor Live version 3.2.1, use:

  ```
  content-type: application/vnd.elemental+xml;version=3.2.1 
  ```
