Products
7100-Series, firmware 7.91.02.0006 and higher
S-Series, firmware 7.72.01.0021 and higher
Matrix N-Series DFE, firmware 7.62.02.0004 and higher

Goals
Firmware versions that support the High Availability Upgrade (HAU) process.
Is Hitless Upgrade supported for my product and firmware?

Solution
Hardware which is upgraded from a particular firmware version, to a particular maintenance release firmware version within the same code track and having the same documented HAU key (visible in 'dir' command output), is eligible to use the so-called "Hitless Upgrade" process - regulated by means of the 'set boot high-availability...' ('clear boot high-availability'), 'show boot high-availability', 'set boot system  <filenamehigh-availability', and/or 'show boot system' commands - in order to potentially keep (rolling) elements of the system up and running during the upgrade, for highest possible ongoing system availability.

Before & After firmware versions which do not have the same HAU key are not sufficiently similar to support this value-added feature.

The following tables are summarized from product release notes.
