But lost User Information ...! Is this normal?
This is intentional, because designers and developers often develop websites in local/development servers with some temporary credentials, then migrate to client's server and create super-admin user for the client with client's email. Afaik, it is not possible to change super-admin's email in backend, that is why the new installation is always clean and super-admin is created again.
If only you have an extended-users configuration with tens or, even, hundreds of users this could create some trouble. Here I have zero experience, maybe @KK could answer better. What I do know is that while extended users setup is configured and created on developer's side, it is very unlikely to have all the users signed up and filled with data. Probably some fake/temporary data is tested. But migration, indeed, should be taken into account. I will address your question to @KK. Thanks!
