Hello, I installed mail server from following the Perfect server Ubuntu with ISPConfig 3 steps. It is running fine but now I need to migrate from Ubuntu to Suse 11.4. Can anyone tell me how can I migrate to Suse 11.4 from Ubuntu 10.04 keeping all the mail users’ information and files intact and the users won’t even notice the difference? NB: I followed the Perfect server Suse with ISPConfig 3 to build my mail server. It works fine. But how can I restore the user information and files in the new server?
