So far in my upgrade, no issues. My main server that hosts the gateway was complaining about something in LDAP.pm, but otherwise everything worked smoothly on both servers:
We assume /etc/openvpn/ebox-dh1024.pem is a Diffie-Hellman parameter file with 1024 byte length. If the assumption is false, please remove it and create a new one manually. If you do NOT do so, your OpenVPN tunnels may be compromised

In fact, things worked so smoothly, one of my servers which, after upgrading to one of the later eBox 1.3 versions, had a load consistently around 3 to 5 is now back to normla 0.00, to 0.25 load instead.
