Therefore, it is best to perform the upgrade when there is no traffic on the server or when it is least impacting on your business operations. Kerio Connect requires a restart during the upgrade.Make sure that your server meets the required system and hardware requirements.Note: You must have SuperUser/root privileges to upgrade Kerio Connect on Linux systems manually. When you are using the administration interface for the upgrade, this package installs automatically. When performing a manual upgrade to Kerio Connect 9.2.7 and above on Linux, first install the cryptsetup package before attempting to upgrade.Users are entitled to upgrade to the latest version that is released during their software maintenance period, even after the agreement's expiration.įor example, if the latest version was released last week and your maintenance agreement expires today, you will be able to upgrade to this latest version tomorrow. This is a good product and I look forward to where its headed.Note: The software maintenance agreement expiration date can be found on the splash screen of the Kerio Connect administration console. For larger enterprises I can see the benefit but for now I'll stay with an albeit 'older' version but one that works. That being said I've been more than impressed by its stability and only wish that Kerio had a more liberal upgrade policy because you either get locked into their 'subscription' or pay nearly the full price over and over and over. To get the full benefit did take some time to pour over the documentation because, to be quite frank, there are some areas that simply are not explained very well or at all. KMS was, for me at least, approachable and easy enough to understand that it took little time to configure a working SMTP/POP/IMAP server with options. Many, while free, took too much of my time away from other tasks in order to manage or study up on, and others were so expensive as to put them out of reach of mere mortals(ex: CGP). I'd searched high and low for an email server that wouldn't require me to be a full time administrator.
