Setting this write-only object initiates a flash-to-flash software transfer between memory banks, with the specific value chosen determining which bank pairing and throughput setting is used. An admin uses this to stage a new software image into an alternate flash bank without disrupting the currently running image, a safer path than downloading directly into the active bank. For example, initiating this transfer to move a newly downloaded image from the primary bank into the backup bank lets the node keep a known-good fallback image available.
