Hi Jon -
Jive Cloud does not have version numbers as they are always on the latest deploy. Historically, we've released updates quarterly to the Jive Cloud service, and those releases are identifies as (Summer, Fall, Winter, Spring).
Jive Custom, or Jive Hosted, is signified by release numbers and the Data Export Service is available to Jive Hosted installations running Jive 7.x versions or greater.
If you'd like to look into possible upgrade options, you might want to join the The specified item was not found. group and check out the The specified item was not found..
That makes sense - thanks.
