If you can do it separately from any systems conversion you will be much happier. Either before or after.
And see if you can keep some of the key minimum editing in or your users will hate you forever. I've heard comments 5 YEARS later about this issue.
So I will add this tip. Keep your user roles simple. Start with the principle of 'least privilege'. It is so much easier to add access than remove it.
