Our IT guy mistakenly set up Windows 2008 R2 Standard Edition instead of Enterprise Edition. The machine has 64GB of RAM, and Standard only supports 32GB, so half of it is unusable.
Is there a way to upgrade to Enterprise Edition without a complete re-install? He has already generated some CSRs for SSL certs and done other work we'd hate to waste. (The cost of the license isn't an issue, just mechanically how to best perform the upgrade.)
