Why do you want to have your license reissued? When you revalidate, the examiner just writes on your license that you have revalidated and that's it. Then your licence shows a MEP expiring the 30th of June 2018, and an IR-ME expiring the 30th of June 2019. Before the end of June 2018, you may revalidate or not your MEP, as you wish, the two things are different.
