Hi
So, basically you want to upgrade SQL server to a newer version, correct?
i think you should post this question on a micorosft forum for better assistance.
As far as i know you can perform an in-place upgrade to SQL Server 2014 using the graphical Installation or you can upgrade using a configuration file.
If instead you want to install SQL on another machine and mugrate the database there i think you have to depoly the new machine, isntall SQL 2014 and follow the Micorosft best practices for the database migration.
