Should we replace OFS by Ecostruxure OPC-UA Server Expert ?

Hi all,

I've been told that OFS was in end of life. The suggestion coming from Schneider was to use Ecostruxure OPC-UA Server Expert which works super fine using OPC-UA. While OFS uses OPC-DA we thing it's a good direction. 

Is there any official statement regarding this ? 

What are the options for customer using OFS licenses via Aveva xml files ? Should they buy a seperate license for the new software ?

Regards,
