A client with a fully depreciated production zBC12 would like to upgrade to a z14 ZR1 of equal capacity. At the same time, they would complete a data center move to a location across the country…

Question

Options

• APurchase a net new z14 ZR1 for installation in the new data center.
• BMES the zBC12 to a z14 ZR1 located in the new data center.
• CMES zBC12 to z14 ZR1 in the current location; then move the z14 ZR1 to the new location.
• DPerform a Migration Offering from zBC12 to the z14 ZR1 in the new data center.

• A
  58% (14)
• B
  4% (1)
• C
  25% (6)
• D
  13% (3)

Explanation

Purchasing a net new z14 ZR1 for the new data center is correct because the zBC12 is fully depreciated, meaning it carries zero residual value - the financial leverage that makes MES and Migration Offerings economical simply doesn't exist here. Installing a new machine in the new data center first allows workloads to be migrated while both systems run in parallel, achieving minimal downtime before the old zBC12 is decommissioned.

Why the distractors fail:

• B (MES to new DC): An MES is an in-place hardware conversion - IBM performs it on the existing machine chassis, so it cannot be executed at a remote, new data center location while the machine sits in the current one. Logistically broken.
• C (MES locally, then move): Two disruptive events (the MES conversion + a cross-country physical relocation) mean more downtime, not less - the opposite of what's required.
• D (Migration Offering): Migration Offerings derive their economic value from the residual trade-in value of the existing machine. A fully depreciated machine has no residual value, so this offering provides no meaningful discount advantage over buying new.

Memory tip: Think of it as the "empty bucket" rule - a fully depreciated machine is an empty bucket (no residual value to pour into a deal), so trade-in-based options (MES, Migration Offering) lose their economic edge. When the bucket is empty, just buy new and run parallel for clean, low-downtime migrations.
