Update from V8 to V11

Hoi;

I'm still using C1-Pro-for-SONY V8 and want to update to C1-Pro-for-SONY V11.

Can I still use the free styles/presets which I downloaded and installed in V8?

What is the best way to update ..re-instal V8 ..download and install V11 or is it possible to use V8 and V11 together.
Or is it possible to install V11 on my desktop and V8 on the laptop?
