How do I update DEV database with most recent copy of LIVE?

Hi,
I am trying to update our DEV with sunday's copy of LIVE db.
I took a cold backup of live db with all the files.
I copied it over to test server. It is exact same file structure.
I have this sql statement but I am not sure that I need to ALTER before starting this sql statement.
Do I need to ALTER anything or I can just fire up this SQL statement?

here is the content of SQL statement:
STARTUP NOMOUNT
CREATE CONTROLFILE set DATABASE "DEV" RESETLOGS  noARCHIVELOG

    MAXLOGMEMBERS 3
