How to migrate SEPM embedded database to SQL server?

I recently installed SEP14 with embedded database.

Now we have to generate reports in a requested format that we can only build with sql statements and therefore I want to migrate the database to an existing MS SQL server.

How can this be done without losing configuration data and connectivity to the clients?

Somewhere in the forum discussions I found a link to a Symantec document, but it was dead.

Thanks and best regards,

Stefan
