We are currently in progress of upgrading our new web-apps to take advantage of .net 4.5
As it stands we can just mount our current sql 2008r2 databases into SQL 2012 and all will work fine after our tests. The question is, should we also rebuild the database directly in 2012 rather then 're-moun' the old ones? Are there any differences to building it fresh in 2012?
Performance? Optimisations? Features?
or is it just a waste of time and go ahead and mount the 'older' 2008 r2 databases?
