[LON-CAPA-admin] System upgrade: moving users over?

Which users are file system authenticated on your system? I assume that
this is only the domain coordinator. As you already created a new one,
you can use this to change the password for the original DC. This allows
you to login again with the old DC user.
All the other users should be able to login though. I (unfortunately
only slightly) remember that we encountered the same issue (-> no roles)
some years ago after having changed nearly everthing (server hardware,
IP address, host name).

This means that a login is possible! If you were not able to login, you
wouldn't see the "No roles" screen but an authentication error message.
So, this is most likely not an password transfer problem.
Have you re-run the loncapa ./UPDATE process (Step 9) again?
I still think that the missing roles are related to wrong host entry
somewhere. Please also check the log files for something like "no
hostname" and make sure that the server's host config file is correct.
Hope this helps,
