Long-term Preservation of the European Hubble Space Telescope Archive

During 2011 and 2012 The European copy of the Hubble Space Telescope archive was migrated from its former home at the ESO to its new location at ESA's European Space Astronomy Centre (ESAC). At the time the Archive was moved with a minimum of changes to the software in order to to minimise the risks involved. Now work is underway to ensure the long term preservation of the European HST Archive. This poster describes how the operational archive is being embedded into the common system infrastructure used by all science archives at ESAC and looks at the challenges and opportunities that lie ahead.
