Restore a database backup of proudction system to a new installation? Works?

Hi Experts,

I want to backup the database(only the database) of the proudction system. Then I want to restore the database to a totally new NW system.

I am thinking this way is not going to work.

First of all, the proudction system has a different system ID with the new system. And the database backup contains the info of the proudction system.

Am i wrong? If this way is working, is there any extra work I need to do?

Best Regards,

Charlie
