Restoring Unity Data/SQL Data from old version to a new one

[jeman85]

How do we backup/restore the Unity Data and SQL database from a Cisco Unity 3.1.3 server for Exchange ( on a Windows 2000 Server Japanese OS ) to a separate Cisco Unity 4.0.3 server for Exchange ( on a Windows 2000 Server English OS ) ?

You can't restore the UnityDB SQL database from an older version of Unity to a new installation - there's many new tables/columns/properties added to the database over versions and items move around between the registry, local files and the database itself - this is why DiRT restricts you to restoring the database to an installation of the same version that was backed up.

To do this you'd do a backup of the 3.1(3) server, install a new 3.1(3) server with the configuration you want (including OS version and the like), restore the bacup to it and then upgrade to 4.0(3). You can't do this in one migration/upgrade/restore step.
