We are currently running FSM 6u6 on SQL Server 2017 and are in the process of upgrading to FSM 6u15 on the same SQL Server 2017. I’ve realized that during previous upgrades (during which we upgraded from SQL Server 2008 to SQL Server 2017) we didn’t update the Compatibility Level of the database storing FSM data.
Currently the Compatibility Level of the database holding FSM data is set to level 100 - is there any reason not to update the Compatibility Level of that database to 140? We’d like to take advantage of newer functions for reporting, and I’m hoping the new cardinality estimator and adaptive query processing feature will speed up performance at least for reports.
If anyone has any experience with this I’d appreciate advice as I’m not a DBA
