Hello Jerold.
as Ranajay was saying there is no link between the two.
SAP Predictive Analytics 2.x and Lumira are now different code lines. New functionality appearing in Lumira does not appear into the Expert Analytics mode of PA (and viceversa). The file pointed out by Ranajay will presumably not change in future version of PA 2.x.
You can install both PA and Lumira on the same machine
