What types of migration are supported from 32-bit to 64-bit?
A. migration of qtrees via QSM
B. migration of volumes via ndmpcopy
C. migration of volumes via SnapMirror
D. Both A & B
E. Both B & C
F. Both A & C
Correct Answer: D
Explanation/Reference:
Explanation:
Volume SnapMirror operates at the physical block level. It replicates the contents of an entire volume, including all Snapshot copies, plus all volume attributes verbatim from a source (primary) volume to a target (secondary) volume. Implicitly, the destination volume will be the same as the source volume. Since C is incorrect, A & B must be correct.
Qtree snapmirror operates at the logical level, so it is unimportant that the destination system has a different volume configuration.
ndmpcopy is similarly operating with data already read from the volume and so the destination volume type is not a consideration.
