A customer currently is running a POWER7 6-core 720 with 3 IBM i cores for production, and utilizing Power HA to a POWER6 2-core server as their backup
machine.
The production machine also has unlimited users, IBM i Access users, SOL, and ILE Compilers. They are only using the backup machine to do backups, but it is
not a CBU; it has only one IBM i and one licensed Power HA core.
The customer wants the backup server to have the same capacity as the production server so it can be a true high availability server.
Which of the following is the correct course of action at the least cost?

A.
Upgrade the POWER6 to a POWER7.
Add two additional IBM i and Power HA Licenses, IBM i and IBM i Access users SQL and ILE Compilers

B.
Upgrade both servers to P0WER8 and transfer all the software to the new POWERS servers.

C.
Purchase a new POWER8 to replace the POWER6 server and transfer the software from the POWER6 Designate the POWER8 as a CBU to the POWER7.

D.
Purchase two new POWER8 servers designating one of them as a CBU.
Transfer all the software from the POWER7 to one of the POWER8 servers and all the IBM i and Power HA software from the POWER6 to the other POWER8
server.
