The HERA straight sections have been rebuilt to obtain smaller beta functions at the IP to increase the luminosity by a factor 3-5. The new IR is based on superconducting quadrupole-separator magnets which have been integrated in the ZEUS and H1 detectors respectively. These have been designed and built by BNL. In total, about 500 m of new accelerator lattice has been completely rebuilt with new magnets and vacuum systems which also include two spin rotator pairs. Many beam dynamic features of the new lattice have been tested in the old IR configuration. Recommissioning will start in July 2001. A fairly detailed recommissioning plan has been worked and will be discussed.
