A customer is planning data migration for a high-end AIX server. The server currently has 61
1 LUNs on non IBM storage and needs to migrate the data to a newly installed XIV storage

system. The customer has asked the technical specialist how the data can be migrated in
the most efficient method possible for this server.
Which option should the technical specialist discuss?

A.
Only 512 LUNs can be migrated at a time

B.
All LUNs need to be allowed to fully synchronize before mapping the server to XIV

C.
All 611 LUNs can be migrated concurrently with the use of multiple migration targets

D.
Only one path to a passive controller is needed if the non-IBM storage has active/passive
controllers
