How to activate my licence Kirby?

1

I just bought a licence of Kirby 3, and I’m using a website that used a 2.4 version of Kirby.
In the website options, here’s what’s mentionnd : “You are using the Kirby trial version
Please, buy a license ›”, I don’t wanna buy it since I already bought it, I’m asking how to implement it or activate it ?

Thank you!

So now you still have a Kirby 2 website, but with a Kirby 3 license?

Edit. in Kirby 2 you have to add the license key in your config:

c::set('license', 'license_code');

Replace K3 with K2 to make it work.
