Kirill We are running 2.11.x clients on 2.5.x servers (Neo 2.0) in TDS environment and haven’t seen any issues yet. Plan is to put it in production in a month or so. We also have 2.11.x servers(Neo 3.1-022). I am will be very keen to test PFL in a mix env of 2.7 and 2.11 clients. If anybody has tested this, please let me know.
