Welcome to immigrationboards.com!
I don't believe so as the visa has already been granted. You are only transferring the initial entry vignette.And also does it matter that I have already turned 31?
I have no idea. I know you can ask for a visa to be granted for a date more than 3 months in advance.Also if it expires does it matter what date I choose for the next vignette or is there a say 3 month or 6 month expiry on the transfer too?
