Hi,
We will continue to support DPS classic for at least year after the launch of DPS 2015, which was in July this year.
However, this doesn't mean that DPS classic will be turn off in July 2016, it just means that we will continue to support it at least until then and probably longer than that.
We will let our customers tell us when they’re done with Classic by moving to the new DPS (2015).
Thanks,
Andrei
