Hi, I have a production server running Debian Squeeze with Dovecot 1.2 I would like to upgrade everything to Jessie, running 2.2 Last time I did something similiar, but from Lenny to Squeeze, the whole dovecot installation broke. Any suggestion on how to upgrade everything ? Can I test our current configuration with a newer dovecot version to be sure that everything would be converted properly with "doveconf -n -c /etc/dovecot/dovecot.conf > dovecot-2.conf" ? Thank you

For good pointers, see http://wiki.dovecot.org/Upgrading it's not complete, but it should give you some idea. Aki

The only way to fix was to downgrade. As this is a production server, I would like to avoid this kind of issue.....

I did it so: + checked out the automated conversation, + each change I made to the conf of Dovecot v1, I read, what to do in v2 and applied the change to the default configuration manually with hints from the step above + once all in place, I started a test system with a bunch of accounts that used all features: sieve, sharing, ... . - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEVAwUBWKRMH3z1H7kL/d9rAQIbBgf/YUDU2IQbb8Uhif9q52y2Rk0eJWZJ0j6X LYEEEyHBFgxQA8YRRrgRwkShRPLXzUKIEmMGGsdyCcxwqZvnufcjWuS76EObs1xw Mg5NWbiwgtx0QrCLGoPt2KAC8h2a27AEETgoiF+WzlNteG/uiI7Yz2nKNXMU2Cc0 8rB9BGs16PAukBE0Zkgs2NLMaFt9JqiRPbHxtGaMrecKPDxx8BusK6zpxq69zUDQ Rzdw21+t7eZhSuSbSbf9N/aZRYtJ8b/2RC4FXNuNDTV6vvVngRkxLJSwwfSMB3hu GheseYUKmq9vQWy+lWL1R9tT5gZgTO1s2kmg4uAhQ0KsQ3k0+aDMEw==rXtr -----END PGP SIGNATURE-----

Just my 2c. Aki
