How can I migrate my exisiting email user to ISPconfig. I have almost 500 users in My mail server. Do I have to create them all from ISPconfig or there is any option to import. Please help
There is no import option yet. You will either have to create them manually in ISPConfig or you use the remoting framework. http://www.ispconfig.org/remoting_plugin.htm
I can manualy create user's but the problem with user's existing password. It is not possible to know the user's password.
If you have the passwords encrypted with the crypt function, you can add al users with "fake" passwords first and then replace the encrypted password hashes in /etc/shadow with the original password hashes from your old installation.
Thanks Tim.. it will work! But another issues with exisiting mail users. My user's use squirrelmail for webmail and they have their existing mail and custom folder in their /home/user .. and also their config in squirrelmail folder.. Is there any way I migrate them ?
I guess you should be able to migrate the complete squirrelmail installation to the new server. You can use your current squirrelmail with ISPConfig too. If you use Imap on your old server, you will have to migrate the imap filders and emails to the new home directorys of the users that ISPConfig creates.
