Attention

If you're trying to upgrade iRedAPD-1.4.0 or later releases to the latest iRedAPD, please check this tutorial instead: Upgrade iRedAPD
We provide remote upgrade service, check the price and contact us.

This tutorial describes how to upgrade iRedAPD from v1.3.x or earlier versions to the later releases, it's applicable on all Linux/BSD distributions supported by iRedMail.

Important Notes

Since iRedAPD-1.4.0, we use Python source file as config file, not .ini format anymore.
We don't need second instance iredapd-rr anymore (it listens on port 7778), just one instance, one listen port 7777 is required.

Steps to upgrade iRedAPD-1.3.x or earlier versions:

Download the latest stable release here: https://dl.iredmail.org/yum/misc/ For example, iRedAPD-1.4.4.tar.bz2.
Upload it to your iRedMail server. Assume it's /root/iRedAPD-1.4.4.tar.bz2 on the server.
Extract downloaded package and move to /opt/, set correct owner and permission:

# tar xjf /root/iRedAPD-1.4.4.tar.bz2 -C /opt/
# cd /opt
# chown -R iredapd:iredapd iRedAPD-1.4.4
# chmod -R 0700 iRedAPD-1.4.4

Generate new config file from sample file, and set correct file owner and permission.

# cd /opt/iRedAPD-1.4.4/
# cp settings.py.sample settings.py
# chown -R iredapd:iredapd settings.py
# chmod -R 0400 settings.py

WARNING: Config file /opt/iredapd/settings.py contains sensitive infomation (username, password), please don't make it world-readable. Permission 0400 is the best.

Open iRedAPD config file /opt/iredapd/settings.py, and sync settings with old iRedAPD config file /opt/iRedAPD-[OLD-VERSION]/etc/iredapd.ini.
- In old version, parameters under [ldap] section are now new parameters start with ldap_.
- In old version, all parameters under [sql] (or [mysql]) section are now new parameters start with sql_.
Remove symbol link of old release:

# rm -i /opt/iredapd               # <- Don't not end with '/'.

Copy new RC script. We have scripts for different Linux/BSD distributions, please copy the correct one for your distribution:
- /opt/iredapd/rc_scripts/iredapd.rhel: For Red Hat, CentOS, Scientific Linux.
- /opt/iredapd/rc_scripts/iredapd.debian: For Debian and Ubuntu.
- /opt/iredapd/rc_scripts/iredapd.freebsd: For FreeBSD. Please copy to /usr/local/etc/rc.d/.
- /opt/iredapd/rc_scripts/iredapd.openbsd: For OpenBSD. Please copy to /etc/rc.d/.

# cp /opt/iredapd/rc_scripts/iredapd.rhel /etc/init.d/iredapd
# chmod +x /etc/init.d/iredapd

Create symbol link to the latest release:

# cd /opt/
# ln -s iRedAPD-1.4.4 iredapd

Restart iRedAPD service:

#
# ---- On Linux ----
#
# /etc/init.d/iredapd restart

#
# ---- On FreeBSD ----
#
# /usr/local/etc/rc.d/iredapd restart

#
# ---- On OpenBSD ----
#
# /etc/rc.d/iredapd restart

If you don't have file /etc/init.d/iredapd-rr (on Linux), or /etc/rc.d/iredapd-rr (on OpenBSD), or /usr/local/etc/rc.d/iredapd-rr (on FreeBSD), it's safe to ignore below steps. But if you have it, please stop service iredapd-rr, then move all enabled plugin names listed in /opt/iRedAPD-[OLD_VERSION]/etc/iredapd-rr.ini to new config file /opt/iredapd/settings.py, in parameter plugins =.

# /etc/init.d/iredapd-rr stop
# rm /etc/init.d/iredapd-rr

Check whether you have check_policy_service inet:127.0.0.1:__7778__ in Postfix config file /etc/postfix/main.cf (Linux/OpenBSD) or /usr/local/etc/postfix/main.cf (FreeBSD), if you have it, please remove it, then restart Postfix service.
