In my remember, current SummaryPages (k1sum0) doesn't use k1nds[0-2] because too many accesses from k1sum0 to NDS interrupts site commissioning activities which depends on NDS.
It now accesses gwf data via GWDataFind server + local NDS2 on k1ldv0.
From the view point of conflicts with the commissioning activities, it's better to use same manner on the new enviroment.
