When I started with SF I had installed MS-SQL Express 2005, now I want to install the Developer Edition of SQL 2005, and remove the Express version in my dev computer.

Is there something I should be doing with the databases I already have in the Express version before or after installing the Developer edition?  specially the SF database.  I just don't want to mess up my SF installation, nore loose any project's database currently on the Express version before removing this version and installing the Dev edition.

Thanks!
