Upgrading SQL Server 2008 to 2008 R2

Question

Currently, SQL Server 2008 (dev version) is installed on my computer. I want to upgrade to SQL Server 2008 R2. How is this possible?

Please support the same with the screenshot to better understand.

thanks

EDIT . I could go to Google Search, but the attached screenshot does not allow me to upgrade to SQL Server 2008 R2 Edition (attached screenshot from SQL Server 2008 Dev Edition). See Text written in the section “Updating from ... 2005”

Answer 1

The option should appear in the "SQL Server Installation Center", as confirmed in the following screenshot and in step 4 of the Microsoft manual at How to upgrade to SQL Server 2008 R2 (Setup)

As an additional note, have you verified that your intended update path is supported? You can find here
