  Besides the development of PQC algorithms, the actual migration of IT systems
to such new schemes has to be considered, best by utilizing or establishing
crypto-agility. Much work in this respect is currently conducted all over the
world, making it hard to keep track of the many individual challenges and
respective solutions that have been identified. In consequence, it is difficult
to judge for both individual application scenarios and on a global scale,
whether all (known) challenges have been addressed respectively or what their
current state is. We provide a literature survey and a snapshot of the
discovered challenges and solutions categorized in different areas. We use this
as starting point for a community project to keep track of the ongoing efforts
and the state of the art in this field. Thereby we offer a single entry-point
into the subject reflecting the current state in a timely manner.
