Hello,
I am considering getting Unity Pro however that sentence is not too clear to me :
"If upgrading an existing Unity license, please enter your serial number in the text field below. The pricing and options will be updated based on the existing license. "
What is considering upgrading and actually a paying upgrade?
1) Moving for example from version 3.3 to 3.4? 2) Moving to Unity 4.0 when it is released? 3) Or just taking add-ons such as Unity iOS Pro?
Thanks
