Dovecot Configuration Upgrader

This tool converts Dovecot 2.3 Community Edition configuration to Dovecot 2.4 Community Edition configuration. This tool is not 100% perfect and can make mistakes. Always check the configuration. If you are using 2.3 Pro, please contact Open-Xchange for assistance in your configuration.

Not every configuration is supported.

If you run into problems, feel free to contact dovecot-ce@dovecot.org and we'll see if it can be fixed.
