HPE Network Switching Professional (HPE7-A08)

Minimal-downtime upgrades on a CX 8320 VSX pair use the orchestrated VSX Live Upgrade, not ISSU — 'issu update-software' is a VSF feature on the 6300/6400, so option D does not apply to an 8320. The documented procedure is to pre-stage the new image in the same boot bank on both peers and then run 'vsx update-software boot-bank <bank>', which reboots the VSX secondary peer first and then the primary. In the exhibit the target image (TL.10.13.1000) is in the secondary bank, so you upload/pre-stage that image to the secondary boot-bank on both switches (A) and then run 'vsx update-software boot-bank secondary' (B). Option C names the wrong bank (primary still holds the older TL.10.13.0005 image).
