Does Drobo DR: Offsite Data Replication work with different drives?

I’d like to purchase two new Drobos. We share media files from a server. I was thinking about purchasing and 8d to upgrade our old drobo connected to our sever and then put an 810N as the mirrored backup connected to the network in another building as backup. Is it possible to setup using Drobo’s automatic Built in Drobo DR: Offsite Data Replication with these two different models?

According to the Drobo Online User Guide

DroboDR is available only for the 5N2 and B810n…not the 8D.
