Problem with Starpi license

My company has a license for strapi 3.
We are trying to migrate to the laster strapi version.
I create a new strapi project with the quick start 4.1.7.
I updated my .env file with the STRAPI_LICENSE I had, rebuiled and restarted but I have the warning:
warn: License expired. Starting in CE
Do we need a new license for strapi 4 or what am I doing wrong?
Thank you!
