VPS License Question

[GVH-Jon]

Hi,

I currently have a VPS Lease LSWS Enterprise License and I have an OpenVZ 4-Core shared VPS with 2GB RAM.

If I wish to upgrade to 3GB RAM, would I have to purchase a 1 Core License or a 4 Core license? I'm sort of confused, because I saw somewhere that it said if you wish to upgrade RAM on a VPS then you'd have to purchase a 1 Core

Thanks,
Jon
