Change Active Roles 6.9 SQL Server

We're looking to change the SQL server attached to our Active Roles Server 6.9 to a new SQL server.

Are there any instructions on how to do this or has anyone done this before? I know this is an old AR version, and am struggling to find any information related to this version.

We can export/import the SQL database OK, but changing the AR connection is a mystery at the moment.
