Currently we have a number of Servers that are using Windows 2016 with SQL Server 2017. The support team want to do an in-place upgrade of the OS to 2019 due to 2016 Mainstream support ending in Jan 2022. I don't want to upgrade the SQL Server versions, so I am wondering if it is Ok to just upgrade the OS? I will obviously be taking backups and the like but just wanted to know if there were any gotchas I should be aware of before agreeing with the OS upgrade?
Thanks
