After a short summary of experience with e^\pm polarisation at the pre-upgraded HERA, the impact of the luminosity upgrade on polarisation is reviewed. Polarisation tuning requires a machine in stable and reproducible conditions, which have not been established yet. Priority has naturally been given to the luminosity operation and until now no attempt has been made to measure and optimise polarisation after the upgrade, but we hope to start as soon as possible.
