Having completed building a new application a customer wanted to upgrade there back-end database from SQL Express to full SQL Server 2005 for licencing issues.
Here’s my walk through …
Having already installed IIS and navigated within a command-prompt to the media (cd “D:AppsSQL 2005Disk 1”). I ran “setup.exe SKUUPGRADE=1”.
I accepted the licencing conditions, and continued installing components
1) SQL Server Database Services
2) Integration services
(resisting the temptation to re-assign the datafiles from the small C-Drive to the larger D-Drive), until Getting to the ‘Instance Name’ screen where I clicked the ‘Installed Instances’ button.
The next screen confirms the SQL Express instance name, I clicked ‘OK’, then with the instance-name autocompleted clicked Next.
In the ‘existing components’ screen I ticked the one box to request an upgrade and clicked ‘next’.
The resulting upgrade is not obvious, however it can be confirmed my right-clicking on the server in enterprize manager and examining the version.
Following on from this SP3 should be applied.
