A valid transfer path forre-using Fibre Channel (FC) cardsduring a controller upgrade includes moving cards from aFlashArray//Mto aFlashArray//XR2 or //XR3.
The FlashArray hardware compatibility matrix supports the migration of specific legacy hardware components to ensure investment protection for customers. The 16Gb Fibre Channel PCIe cards originally deployed in FlashArray//M controllers are physically and electrically compatible with the PCIe risers found in the FlashArray//X R2 and R3 generations.
When performing a "Stateless" upgrade (where the chassis/controllers are replaced but data drives or cards might be retained), the Implementation Engineer can physically transfer these FC HBAs from the retiring //M chassis into the new //X chassis (assuming the target chassis has the appropriate open slots and the cards meet the minimum speed requirements, typically 16Gb or 32Gb). Option B is the most comprehensive correct answer recognized by the exam, confirming that the //M series cards can land in either of the specified //X generations (R2 or R3). Option C is also physically possible but the specific exam context for "reuse" highlights the inter-generational leap from M to X.
