Following an upgrade of VMware Cloud Foundation (VCF) to versions 4.x, 5.0, or 5.1, the SDDC Manager licensing mode automatically and unexpectedly switches to Subscription Mode.
VMware Cloud Foundation 5.0
VMware Cloud Foundation 4.x
This is a known issue specific to VCF on VxRail environments. If the environment is upgraded to the affected VCF versions without explicit license keys added prior to the upgrade, the system's fallback behavior defaults to Subscription Mode instead of retaining the Perpetual state.
There is currently no permanent resolution for this behavior. VMware engineering is aware of this issue and it is scheduled to be addressed in a future release of VMware Cloud Foundation.
