Hello,
I've installed Iredmail 0.9.5-1 about one month ago when SOGo package was at 3.1.2 release. Now it is available as 3.1.3 with many bug fixes from the repos. Is it ok to upgrade as a normal ubuntu package (apt-get install sogo) and applying all the new configuration files made by the distributor? Is it the correct way to mantain all the packages installed by Iredmail also up to date to the latest release? I know this doesn't change Iredmail release but I'm not sure if Iredmail installation makes some customization which could result as broken after a package upgrade.
I've a problem with the new SOGo version (script for updating database schema) and I don't know if it is right what I've done.

Thank you
Best regards
