You can update sites running in an evaluation mode to use a dedicated HCX license or activation key.
This procedure is applicable to HCX Connector and HCX Cloud Manager installations where the vCenter Server is not licensed yet licensed for VMware Cloud Foundation (VCF). If the vCenter is licensed for VCF, HCX sites running in evaluation mode automatically interherit that license.
Note:
If your site is activated with an evaluation license prior HCX 4.9, that license is updated to Evaluation Mode upon upgrading.
