--------------------------------
To install any release of Firmware after 2.10 (2019) requires an active ESS/SUM entitlement on the subscriber. This can be purchased for n number of years and new subscribers will have a 5 year (I think that's right) entitlement included.
Old firmware, even back to R1.12.17 can be supported from a Code plug / Configuration view point on current CPS/RM, But Newer Firmware requires the same or newer version of CPS / RM.
The last version released with the older CPS (16 Build 828) is R02.09 (2018)....
