A customer has two HP 3PAR T800 systems with Inform OS v2.3.1 in two separate locations
Data is being replicated between systems using Remote Copy. The customer wants you to
develop a plan for upgrading the environment to the HP 3PAR OS v3.12. What should you
consider in your planning?

A.
All participating systems must be upgraded to the same major OS within 5 weeks.

B.
It is not necessary to stop the Remote Copy groups for online updates.

C.
Downtime must be scheduled because you cannot upgrade online from v2.3 1 to v3.1 2
directly.

D.
Necessary updates to the hosts as required in the Interoperability Matrix can be installed
after the Inform OS update.
