Our end user have existing C40 unit which supports TCNC sw and is currently using TCNC6.2.
their HO tried upgrading their unit to TC7.1.4.908e4e9 and it’s successful unfortunately the "missing RK" message appear.
I believe the TCNC is totally different from TC platform.
We also encountered this to other client, wherein the client wanted to upgrade their unit from TCNC to TC; but the difference is that the upgrade is not successful.
Thanks and hoping for your usual assistance.
