I already have an established server setup with users (mail.server1.com). I'm trying to setup another server (mail.server2.com) but when I run the install script, It finds the current install and then I get this rotating error.

Do you wish to upgrade? [Y] N

*** WARNING - you are about to delete all existing users and mail

Delete users/mail? [N] N

How am I supposed to proceed to add the 2 server?

Any help is appreciated.
