We have MSSQL 2008 R2 SP2 running on Windows Server 2008 R2 (64 bit). We want to upgrade the OS to 2012 R2 and MSSQL to 2014. Can this be done? and if yes then which one from the below options are recommended?
a. Upgrade the DB to 2014 first and then upgrade the OS
b. Upgrade the OS to 2012 R2 first and then the DB
