I did a similiar thing in 2002, but transfered from LTN to LGW (although I left in 2003). I am guessing that it is the same comapny that you are with? They sorted out all my paperwork for a new ID, all I had to do was arrange the appointment to pick it up.
I have a few friends at EMA, if you have any other questions, give me a shout and I'll ask them for answers for you.
Happy flying!!!
