I'm trying to do the upgrade but when it asks me for the Product Key for the current version, I can't find it. When I go on the MSDN website for it, it says that a key is not necessary for this product. So I'm at a standstill. Do I need to do the upgrade directly from the Enterprise ISO instead of from the Standard SQL Server Installation Center Maintenance Edition Upgrade option? How else can I get the product key?
Or when it asks from what version I'm upgrading, can I select Express or Evaluation where it doesn't require me to put in the current product key? Will that affect the upgrade?
Will I definitely need the ISO? The same deal with that is that it says the product key is not necessary on the MSDN website since we have an EA.
