Hi, I would like to move ispconfig on an other server… And for this, I've to reconfigure everything, and there is 2 change The server is actually on Debian 6 and the new one will be on Debian 7 ;-) 1) I use courier and I saw that it's better to use dovecot, more easy and flexible to configure 2) Nginx take less resource than apache… So I would like to have some advise and if it's possible to migrate from apache to nginx / courier to dovecot. Thx !
