A customer wants to migrate Hitachi AMS2100 data to a newly acquired Hitachi Unified Storage (HUS) system. Which statement about the migration is correct?

Question

Options

• ATrueCopy between the AMS2100 and the HUS can be used.
• BTrueCopy between the AMS2100 and the HUS cannot be used.
• CModular Volume Migration between the AMS2100 and the HUS can be used.
• DTrueCopy Extended Distance can be used for a non-disruptive migration between the AMS2100

• A
  82% (28)
• B
  9% (3)
• C
  3% (1)
• D
  6% (2)

Explanation

TrueCopy supports replication between compatible Hitachi storage platforms, and both the AMS2100 and HUS support TrueCopy, making cross-platform synchronous replication - and therefore migration - possible between them. Option A is correct.

B is wrong because it directly contradicts the compatibility that exists; TrueCopy is precisely the tool designed for this kind of heterogeneous Hitachi-to-Hitachi replication.

C is wrong because Modular Volume Migration (MVM) is designed for intra-platform or same-family migrations (within the modular storage line), not across different product families like AMS to HUS.

D is wrong because TrueCopy Extended Distance (TCE) is the asynchronous variant built for long-distance replication over wide-area networks - it is not the standard recommended path for a local migration between these two platforms, where regular TrueCopy suffices.

Memory tip: Think "TrueCopy = True Cross-Platform" - whenever you see two different Hitachi platforms that both support TrueCopy, standard TrueCopy is the migration bridge. Reserve TCE for the "distance" clue (WAN, long-haul), and MVM only when staying within the same modular family.
