Just starting to think about migrating 2014 AG cluster to 2017.  2014 cluaster is the classic 2 HA node + 1 DR node.  We need to maintain the 2014 because it's hosting apps.  We want to introduce a 2017 cluster, but we want to minimize expense of hardware.  Can 2017 be install side-by-side on the the 2014 DR node, and that node serve as DR for both 2014 and 2017 clusters? Not even sure that makes sense, but need to ask.  Thx.
