Migrate method TFS 2008 to 2012

 

Currently we have a TFS 2008 server running on a Server 2003 R2 platform with a local install of SQL Express 2005. We would like to migrate our TFS to the new 2012 version, in order to do this I already installed TFS 2012 on a new server with a remote SQL database (SQL 2008R2).

 

Could you tell me what's the best way to migrate our TFS data? I already checked some posts related to this subject but they are all based on migrating TFS from a SQL 2008 database.

 

Thanks in advance.
