Hello,

You'll find this information in the file UPGRADING and in SQL/mysql.update.sql, e.g.:

-- Updates from version 0.3-stable

TRUNCATE `messages`;

ALTER TABLE `messages`
    ADD INDEX `index_index` (`user_id`, `cache_key`, `idx`);

ALTER TABLE `session`
    CHANGE `vars` `vars` MEDIUMTEXT NOT NULL;

ALTER TABLE `contacts`
    ADD INDEX `user_contacts_index` (`user_id`,`email`);

-- Updates from version 0.3.1

/* MySQL bug workaround: http://bugs.mysql.com/bug.php?id=46293 */
/*!40014 SET FOREIGN_KEY_CHECKS=0 */;

.... and so on

So the best way is to upgrade your existing version.

hello

we plan to migrate our mailhub , the actual one runs roundcube 0.3
and the new on will run 0.5 version.

I would like to import mysql data from the old one to the new one.
what would be the best way to do so ?

Thanks a lot.
