Hello again,
You can't move the 6.3 sql database to a sql 2012 server, you need SIM 7.1 at least for sql 2012 support. You could perform a migration to 7.0 and then to 7.1. Then you can copy the database to a new sql 2012 database.
Now you need to edit some config files to point to the new database. You can find info on changing the datebase name or location. https://www.google.nl/url?sa=t&source=web&rct=j&ei=XyNeVbryFsj1UOa-gWg&url=http://h20565.www2.hp.com/hpsc/doc/public/display%3FdocId%3Demr_na-c03225518&ved=0CB0QFjAA&usg=AFQjCNFiTpMGe33BV0g6FImZ9QdUEBGWLw&sig2=NqD0rHjU5dhVVQChorCrHA
