I started with a 6.x.x on CentOS 5, and I upgraded it up to 7.2.0. So it is not the same setup as yours... From my notes, I did: yum install nc libidn-devel gmp-devel perl-Net-Ident perl-Razor-Agent \ perl-Encode-Detect ./install.sh --platform-override Change domain name? [Yes] Create domain: [<OLD>] <NEW> 3) zimbra-store: Server mode: mixed cd /usr/sbin mv sendmail sendmail.old; ln -s /opt/zimbra/postfix/sbin/sendmail sendmail Copy ssl keys to /opt/zimbra/ssl/zimbra/commercial/ commercial.key commercial.crt commercial_ca.crt /opt/zimbra/bin/zmcertmgr verifycrt comm commercial.key commercial.crt /opt/zimbra/bin/zmcertmgr deploycrt comm commercial.crt commercial_ca.crt Change ports: zmprov -l gs <FQDN> | grep "Port:" zmprov -l ms <FQDN> zimbraMailPort 80 zimbraMailProxyPort 0 \ zimbraMailSSLPort 443 zimbraMailSSLProxyPort 0 zmprov -l gs <FQDN> | grep "Port:" zmcontrol restart JD
