Hi!

To make migrating from Dovecot 2.3 to 2.4 a bit easier, we are now 
providing a tool that helps upgrade your existing configuration. The 
tool allows you to upload either a full dovecot.conf or selected 
ancillary configuration files from a 2.3 setup, and will attempt to 
convert them accordingly.

You can find the tool here:
https://dovecot.org/upgrader/

We do not store any of the configurations processed by the tool, nor do 
we track who uses it. It's offered as-is, without any warranty or guarantee.

If you run into any issues, unexpected results, or have feedback about 
the tool, please let us know — it’s very much appreciated.

Please note that the tool can make mistakes, so we strongly recommend 
carefully reviewing and testing the output before using it in production.

There are currently no plans to release this tool as open source.

Regards,
Aki Tuomi
