Discontinuing one Unit and Organizing another Without Changing Task or Purpose

Anyone been in a unit that discontinues and is then organized as another unit without changing the task and purpose and with limited changes to the TDA/TOE? Not a simple re-flagging from one named unit to another, but a total discontinued/organized event?

The 4th Battalion, 10th Infantry Regiment, a TRADOC training support battalion has been officially "Discontinued" as of 01 October 2014 and the Special Troops Battalion has been "Organized" as of the same date.
