Hi, Faddey.

You can upgrade your license using the order form. You must login with your email and password, and then you will need to fill in the license key of the license you want to upgrade.

To finish the installation process; launch the setup program and follow to the suggestions displayed on the screen.
Make sure you choose to change from the current version during downloading.

is it possible to keep Running VIP10 AND VIP11 on 1 machine?

can they be installed next to eachother on 1 machine, I mean should this theoretically be possible?

It is not only theoretical possible, it is also practically possible. Moreover if you install the vipLaunch utility and have prolog files bound to it (this happens by default when installing vip 11). Then you can "mark" each project to open in either Vip 10 or Vip 11. Just double click a project file an when the vipLaunch utility gives you the choice you can "fix" your choice with the "pin".

Should you later wish to choose differently for a certain project you right click it in the explorer and use "Open choose" in the menu.
