From SQL Server, you can perform a backup of the new database, restore the new database to the server, and delete the old database. You can do that manually or in a scheduled job.

Perhaps a more common approach to synchronizing databases is using "replication". While this can become quite complicated, you can probably use the basic functionality. About.com has a short description of it here.
