Hi, I already read and click on "Reissue License" Already.
But i still not get License Files So how i gonna upload into the Proxmox Mail Gateways??
as the picture below....

You have to upload the superscription key, there is no license file.

Maybe you still use V4? This subscription key is for V5 only.

=> upgrade to V5.
Hello, I want to do the same, but my licence was cancelled on proxmox shop in profit of a licence through a reseller since i live in Switzerland.
So i need to wait business hours to reinstall on another host and move licence
Is it still mandatory for me to go through reseller or can i migrate to proxmox shop again ?
