Management Reporter Legacy Provider

Good Morning,

I had the following two questions regarding Management Reporter 2012:

1) If one uses Management Reporter with Dynamics GP 2013 R2, until when will the “Legacy Provider” be supported? Basically, when will we need to deploy the Data Mart Provider?

2) From my understanding, GP 2015 does not support the Legacy Provider, right?

Thank you for your time.

Regards,

Joseph
