Upgrading one edition of Microsoft SQL Server 2008 to Another Edition of SQL
Server 2008
There are two options for upgrading to a different edition of SQL Server 2008:
1) Use the Edition Upgrade Wizard from the SQL Server installation media. See
this link
for step-by-step instructions
2) Run setup from the command prompt with the SKUUPGRADE=1 parameter. See
this article
for more information.
The following is an example of the second option:
