Question

What is mortgage porting?

Answer 1

If you have a portable mortgage you can take the same mortgage with you if you move house.

If you mortgage is not portable when you sell the house you have to pay off the existing mortgage and reapply for a new one for your new house

Answer 2

It means you can continue with your existing mortgage if you sell and buy another property.  In theory it should mean avoiding a credit check (required if you wanted a new mortgage, even with same company) and arrangement fees, discharge fees etc.  Situation may vary if you need to increase loan amount (some lenders may still require a credit check if the required amount goes up).  I would expect a mortgage today to be portable unless it was something unusual.
