VCOPS and VROPS Interoperability Matrixes and ESXi

Hi,

When i select VCOPS and any version and then select VMware ESX/ESXi it does't list any ESX host as compatible.

When i do the same for VROPS it shows only ESXi 5.5 U1 and U2 as compatible.

Does anyone know what does this mean? Does it mean VROPS vapps can only be install on ESXi 5.5? or does it mean it can only collect data from ESXi 5.5?

I can see from another thread Re: Moving to vROPS 6.0 - ESXi 5.1 they mention they don't have any issue collecting data from ESXi which leads me to believe the interoperability matrix is incorrect?

Thanks
