We are planning a migration of our SQL 2012 from Windows 2k8R2 to Windows 2016.
I was told I should notice flag 9481 Cardinality Estimation.
Is there anything else I should be aware of or check\test before doing the migration?
(For sure we will first do the migration on our Test environment, but as we don't have automation on it, it doesn't really check the whole system)
