Upgrading

When you run the ClarkConnect installer, make sure you select the upgrade option (see adjacent screenshot). As with any upgrade, please backup any critical data.

apt-get update
apt-get dist-upgrade

	Warning!

Upgrading to 4.0? Please review the Software Package Notes. For the impatient: Virtual domains are no longer supported. The Community Edition allows a maximum of 10 mailboxes. The Enterprise Edition includes 10 mailboxes - additional mailboxes can be purchased. The mailbox upgrade requires special care -- see documentation. If you have configured the ClarkConnect system via the web interface only, the configuration files will automatically be upgraded. If you have made changes via the command-line or the Webmin tool, double check your custom configuration after an upgrade.

User Manager

If you are upgrading from a previous version, go to the web-based administration tool to review the user manager. You may be required to perform one or more of the following actions:

Webmail

The default webmail system in ClarkConnect 4.x is powered by Horde. Please review the documentation for how to access the webmail system.

Web Proxy

The web proxy server only accepts requests from the local LAN. If you have virtual LANs or other LANs behind your ClarkConnect system, you will need to edit the proxy server configuration file.
