Installing SQL Server 2008 R2 as Install OR Upgrade
I have an application that we have been distributing with SQL Server 2008 and we would now like to upgrade our users to SQL Server 2008 R2. I would like the same installation program to be run by old users (who will be upgrading) and new users (who will just get a full install of R2).
The problem is that in the SQL Server 2008 R2 Redistributable, I must specify either "/ACTION="Install" OR "/ACTION="Upgrade".
I would like the SQL Server 2008 R2 Command line parameters to be different depending upon if a prior version of my SQL Server instance is already installed or not.
I can't see any way to make the command line conditional. Alternatively, I had hoped to be able to create a copy of the SQL Server 2008 R2 Redistributable (one for a full install and one for an upgrade) but I couldn't see a way to do that either.
Any ideas?
