I am upgrading SQL Server from 2008 R2 Standard Edition Service Pack 1 to 2008 R2 Enterprise Edition as per the instructions at Upgrade to a Different Edition of SQL Server 2008 R2.

In the past whenever I have upgraded software in such a manner, I had to re-apply the service pack.

Does a SQL edition upgrade require a service pack re-install ? The MS documentation doesn’t talk about it. 

select @@version

after the upgrade gives me

    I don’t believe the service pack needs to be re-applied – if you run the service pack setup it shouldn’t identify this instance as a valid target since the @@VERSION is already at the SP level.

    That said, why not just apply Service Pack 2 and Service Pack 2 Cumulative Update #1?
