How to port/transfer a mobile phone number

Hi Folks
My elderly father has 2 pay as you go mobile phones - one with Lycamobile and the other with Vodaphone.
He would like his Lycamobile number to be transferred to Vodaphone, so he only has to carry one phone around with him.
Could someone kindly suggest the quickest and easiest way to do this?
Thanks

I wish to port-out my number to another service provider. How do I do that?
