restoring Domino 6.0

Hi

We are trying to restore a server that was using Domino 6.0

As we understand, this is quite easy, since what has to be done is simply:
1- restore OS
2- Install Domino 6.0 normally (exactly as the first time) and running it
once just to finish initial configurations.
3- Replace the "DATA" folder with a proper backup.

This will keep databases, but usernames, passwords, configurations and
everything else.. right?

Is there something missing here? Something else to take into account?

Thanks all
