[horde] Migrating question

[Bo Lynch]

Hello everyone. I have a hopefully simple question. I have an installation
of squirrlemail+Postfix+Dovecot+Spamassassin on a CentOS box that we have
been using for many years now. I just ran across horde and would like to
experiment with it. Is it possible to have it live along side of my
squirrelmail install. Meaning have users using both squirrelmail and
horde?
Thanks so much for sny info.
