Additionally, it was announced at the 2016 Microsoft Dynamics Technical Conference that WMII will be deprecated and replaced with the Advanced WHS module and the Enterprise POS (ePOS) will be replaced with the Modern POS (mPOS) and Cloud POS (cPOS) in AX 7. These deprecated features will still be supported in pre-AX 7 releases but will not be supported in AX 7.
