I have a couple of rigs with HD10 (HD4s) and TDM interfaces. I know TDM is dead in PT 11. However, if I wanted to upgrade to PT11 would I be needing to purchase the PT10HD to PT11HD upgrade? In case of doing so, and I pay the $599 update, will it even install in a system which doesn't have an HDX or HD Native interface?
in other words, will PT11HD without an interface attached run as PT11 native and will in fact install at all?

I ask because I am not in a position to upgrade the hardware of these rigs right now, but may want to upgrade to PT11 especially because you can ran both PT10HD and PT11 concurrently and would like to use PT11's functionality.

I am not sure you can upgrade from PT10HD to PT11 running native... and plus I would loose my upgrade to PT11HD for when I do upgrade the hardware to HDX.

Any help is gladly appreciated!
