still waiting for pip medical

hello I live in the dh area and claim dla mobility high rate lifetime award. I am still waiting for a claim form to transfer to pip I've heard that the last medicals were to be completed by 30th September 2017. but i suppose they may be a few months behind schedule. also i am in the esa support group, and hcp stated in her report recommend reassessment after 2 years.but have not had a medical esa since then and that was 5 years ago. i am not complaining, but i do still feel jumpy when the post arrives.
