Upgrade SQL before upgrading EV to 11.0

Hello,

I am currently working through upgrading EV from 10.0 to 11.0 in my test environment.  The current EV server is a Windows 2008 R2 SP1 server with SQL 2005.  When I run the deployment scanner for EV 11.0 it fails on the version of SQL.

How do I upgrade SQL 2005 to SQL 2012 and convert the databases so I can move forward with my EV upgrade?

Thanks!
