Hi,
yes, upgrade from v3 to v4 is free.
Your commercial v4 licenses are perpetual, and will be always yours.
Now you have some possibility to update your licenses to v2020.
If you want to use new versions, you can purchase an annual Enterprise subscription update for 199€, but at the end of the annual maintenance, your licenses will go back to v4:

if you want to upgrade also your v4 perpetual licenses to perpetual v2020, the upgrading path is more expensive, to know the price, please visit the following link:

About Studio licenses, they can work with versions from 3.08 to 2020.1, like Enterprise licenses.
If you don't have more than 2x GPUs and you're not interested in Net rendering, you can buy an annual Studio subscription for € 199 or pay € 19.99 monthy:

If you have more than 2x GPUs and you need Net rendering, you can buy an annual Enterprise subscription for € 299 or pay € 29.99 monthly:

Note that all upgrade paths are offering you the possibility to use any kind of Octane DCC plugins (including C4D), and also ORC Octane Render Cloud subscription (render credits need to be purchased separately).
