2.0 node not being treated as a 2.0 node in a 2.0 cluster, XDCR and Views tabs have vanished on that particular node as well.

XDCR cluster setup:
c1 : c2 :: 4 : 4
bkt: c1 <--> c2
ubkt: c1 ---> c2

bkt in heavy DGM >> Active Resident Ratio: ~20%
ubkt in even heavier DGM >> Active Resident Ratio: <10%

c1: 10.1.3.235, 10.1.3.236, 10.3.121.126, 10.3.2.54
c2: 10.1.3.237, 10.1.3.238, 10.3.121.127, 10.3.2.55

• Message seen on UI: NOTE: need all 2.0 nodes to enable 2.0-only features
• XDCR and Views tab absent.
• About says: "Version: 2.0.0 enterprise edition (build-1968)"
