Hi, I want to set up a new server with ispconfig to substitute an email server without ispconfig that I have now in production. The problem is that I have to migrate about 3000 users from the current system to the new ispconfig server. There is only one site on this server. I can extract the users of the current system to a txt file. Is there a way to read this file and add the users to the new ispconfig server? If so How?
