I configured a ubuntu mail server about 1 and a half years ago. It was running fine. But after a sudden power loss the os suddenly fails the start up programs. Sometimes the apache works fine but the sql dont work. After restarting the server it cant mount the "/". It tries the fix it. These sort of problems... So now I want to migrate the mail server to two new machines. I have installed Ubuntu mail server and Suse 11.4 mail server. So, how can I migrate all my user data and files in the new servers. Where the user will not find the difference...
