Hello, when I tried this last year (this was on 5.2), it would not upgrade with the hitless-upgrade command. After rebooting the standby module with reboot-standby it did not come up due to a version mismatch with the active management module. I am still waiting for the first successful hitless upgrade, unfortunately this is not always possible even within a version tree. This is a citation from NetIronUnified_05300b_UpgradeGuide.pdf, page 29: Hitless OS Upgrade support limitations Depending on the software version, Hitless OS Upgrade has the following limitations: • Hitless OS Upgrade is not supported for R05.0.00, R05.0.00a, R5.2.00b, R05.0.00c, or R5.2.00d, R5.2.00f, or R5.3.00a and R5.3.00b. • Hitless OS Upgrade is not supported for releases prior to R05.1.00d. This includes R05.1.00, R05.1.00b, R05.1.00c and R05.1.00d. By the way, hitless switchover always works well.
