I have installed sharepoint 2007 SP2 with SQL Express 2005 of course all sharepoint DBs are in SQL Express 2005, I would like to upgrade the Express 2005 to SQL Server Enterprise R2.
Here's what I did so far but withouth any luck:
1. I Installed SQL Express 2008 after the installation, I ran the installation process and choose upgrade, at the step where I should select the DB Instance, the instance of SQL Express is not shown. It only display the instance of SQL 2008 Express that was created during the installation.
2. Since I have no luck with #1, I installed SQL Server 2008 Ent R2, however it only recognize the instance of SQL Express 2008, and the instance of SQL Server 2008 R2.
Any help is highly appreciated.
