Asking here, because my vendor never really gave me a clear answer.
We purchased 2 CPU licenses of SQL back in 2010-ish, and had Software Assurance for the first 3-4 years. I forget at this point. We opted not to continue the SA (despite my recommendation to keep it).
We are still using SQL 2008 R2 because our vendor application doesn't officially support 2012+
We do optionally have access to SQL 2012 and 2014 from our SA, and our licensing portal shows 8 core licenses available. Apparently there was an auto conversion that took place from 1 CPU to 4 Cores when 2012 was released.
What I need to know... is if my existing server, running SQL 2008 R2 that has gone unchanged since initial purchase is still compliant, or do I need to now have enough per-Core licenses to cover the hardware it's running on?
If the latter, Microsoft really screwed...
