End- users need to be aware that their data is being migrated and once the data has been
migrated they need to check that they can access the data. It is worth considering providing
training for End-Users so that they can learn the new features of their environement. Take into
account that End-Users may be away for an extended period of time, for example maternity
leave or long term ill health. Eventually you will need to decide what to do with the original
Source environment.
