Trying this upgrade with "SQL Server Installation Center" (starting SQLEXPRADV_x64_ENU.exe in Windows Server 2008 R2 Standard) and using the choise
"Upgrade from SQL Server 2005, SQL Server 2008 or SQL Server 2008 R2"
When upgrading there comes in "Upgrade Rules" step the following error:
Rule "SQL Server 2008 R2 Service Pack 1 or later is required for upgrade." failed
"Install SQL Server 2008 Service Pack 2 or later ...."
But there is no SP2 for 2008 Express ?
This same error came also if I first upgraded
SQL Server 2008 Express R2 to SQL Server 2008 Express R2 SP1 and then upgrade this to 2012.
How can this update be done ?
