As you can see in the attached machine_ids.txt file...

UMN1 -- Consistent on i86 across all FNP versions. Consistent on x64 across all FNP versions. Not consistent across platforms.

UMN2 -- Seemed to be consistent across platforms and FNP versions at least until 11.13.1

Answer

In 11.12.1, we updated the mechanisms by which we extract ethernet information on Window to use WMI. In a small number of cases, this might cause UMN2 to change across a FNP upgrade.

We recommend producers typically allow for a small percentage of lifecycle operations being denied by FlexNet Operations (by having extra licenses available).
