eSIM Transfer iPhone Air to iPhone 17 Pro

Hi there
I currently have my Lebara number on a eSIM on my iPhone Air, however I fancy changing over to the iPhone 17 Pro and I was wondering how easy is it to transfer over and is it possible with the built in transfer on the iOS.
I recall doing it pretty seamlessly when I was with EE on my old iPhone 15 Pro to iPhone Air.
Thanks

Well it Lebara doesnt support eSIM device to device transfers. I have contacted customer support and they say they will issue out a new QR code within 24 hours. Guess I will have to wait patiently.
