There shouldn't be, you could try doing it from CLI. [URL]
I am planning SAN copy push from VNX8000 to Xtremio X1 array. I did initiators zoning. I could see VNX SP WWN's in XIO but XIO WWN's are not seen on VNX. I got 2015 document. Its not helpful for Xtremio. I have done sancopy before with vmax and unity. With Xtremio WWN registration in VNX i have trouble. I tried to manually register Xtremio WWN in VNX, it still shows not logged in.    Please let me know what can be done
VNX to Xtremio Migration
