The version change check that appears when you install SQL2005 skuupgrade=1 A workaround for the problem _mssql2005

Because a component to install SQL is not installed, you decide to uninstall SQL and reload it again, prompting you when you reinstall:
Version Change check
To change an existing instance of Microsoft SQL Server 2005 to another version of SQL Server 2005, you must run SQL Server 2005 Setup from a command prompt and include the skuupgrade=1 parameter

Action method:
Run the command prompt as an administrator, locate the directory of the SQL Server-side installation files Setup.exe file, and then add the parameter skuupgrade=1.
Example:

H:\>CD SQL Server x64
H:\SQL Server X64>CD Servers
H:\SQL Server X64\servers>setup.exe skuupgrade=1
......

This is the way to install, and then the version change check is not warned.
