Hello,
I'm running SQL Server 2008 SP3, Standard edition and trying to do an "upgrade in place" to SQL Server 2012 Enterprise edition. The operating system is Windows 2008 R2 Standard, SP1. After the "first pass" through the upgrade process I ended up with SQL Server 2012 Standard Edition (which I thought was odd since I'm using an Enterprise license key -- I had assumed it would upgrade me straight to Enterprise), and then I read that I have to run the setup again and choose Edition Upgrade to go from Standard to Enterprise. Anyway, after running Edition Upgrade on the new SQL Server 2012 installation it completed with no errors but I'm still left with SQL Server 2012 Standard edition (so it essentially did nothing). My company purchased enough Enterprise licenses to upgrade five of our servers, and I've successfully upgraded three of them to SQL Server 2012 Enterprise using the "side by side" method already, but we don't have enough storage on our SAN to do these last two "side by side" because the databases are quite large.
Any ideas?
