Move SQL database

Move SQL database

We currently have Netflow Analyzer running on a server with the SQL database on our SQL 2005 server.  We want do decommision the SQL 2005 server as we are replacing it with a SQL 2012 server.
I know I can detach the database file from SQL 2005 and attach it to SQL 2012.  How do I tell Netflow to look to the new SQL server?
