People here are asking me about reasons to upgrade from our 7.1/7.2/7.5 hybrid platform, to an 8.x release.
Where do I could find deeper commercial-tech informations?

Except the fact it’s out of support and end of life ? 
Not sure there’s any documentation to justify an upgrade.
Here’s something to start

Thanks, N3v. You know… to us the reason for an upgrade is clear, but when it’s about speaking to your chief, every word you say, is transformed in something like: “ROI… roiroiroiroi, roi…” 
I’ll read those docs, if have other, they’ll be appreciated.
Regards.
EDIT
p.s. how about Win 10 support for GVP & related tools?
Eclipse is supported on Win10.
