We are installing a new PlateSpin appliance received with ESXi 5.5 & forge 11.1; tried to add workload from a Hyper-v 2016 server but failed

Opened a support ticket: rebuild to 11.3 and ESXi 6.5 is required

Question: do we need to pay for the upgrade licenses: we have the Windows 2012 R2 license key shipped with the hardware but what about the license of ESXi 6.5 and forge VM?

Thanks in advance
