That's the choice I've been given. 1 month into work at a small business with 1 well used 2008 r2 SQL Server (average 9k transactions/sec. with sustained periods of 20K mainly due to BizTalk EDI. 3 db's around 100 GB, 12 smaller ones, Hyper V environment not efficiently configured (1 lun to rule them all)
Which would you choose? What other questions would you ask before deciding? (we use SQL server very generically).
My vote would always be for the latest version simply because you get to use much better features and a lot more powerful database engine. So, I would suggest, go for SQL 2016 ( or if possible SQL 2017 as its already on GA).
Need to be just aware that standard edition comes with resource limitations ( Max: 128 GB RAM, 24 core processor ).
Main item to think about is if the application would support SQL 2016 or SQL 2017.
Great point on the 2017 GA. I've been told the 2016 licenses have already been purchased, but if we are doing this it's worth the ask if 2017 is an option.
