This is our setup:
A vCenter 6.0 running on a ESXi 6.0.
We have another ESXi host running 5.1, and would like this host to be managed from the vCenter 6.0
When adding the host to the cluster the following error is produced:
The VMware vSphere 5 Hypervisor license for Host [HOSTIP] does not include vCenter agent for VMware host. Upgrade the license.
The licenses for the ESXi 6.0 server are:
VMware vCenter Server 6 Essentials
VMware vSphere 6 Essentials (unlimited cores per CPU)
The licenses for the ESXi 5.1 server is:
VMware vSphere 5 Hypervisor Licensed for 1 physical CPUs (unlimited cores per CPU)
What is required for the ESXi 5.1 to be managed by the vCenter Server 6.0?
