How to move data from an old verson

[sepehrmm]

I want to move my old iRedMail installation on an old server to latest version on a new server, on  the old server I have roundcube 0.5.3 and on new server I have 0.9.5.
I've read Upgrading Roundcube wiki page but it's all about how to upgrade an old version to new one not moving data between two version.
so I want to know what are the steps I should take?  which database tables I should move? and etc.

The simplest way would be to upgrade the database from the 0.5.3 to 0.9.5.

The simplest way would be to upgrade the database from the 0.5.3 to 0.9.5.

so it's enough to move records from old tables to new ones.
there isn't any major incompatibily between schemas of tables? do you have done such migration yourself?
isn't there any official guide for migration between versions?

You would need to upgrade the database schema, the SQL files are in the SQL folder.
