Important Notes for SQL Server 2014 Users

Migration and upgrade considerations

Identify: capture slow query plan and last compile time (sys.dm_exec_query_stats + sys.dm_exec_sql_text + sys.dm_exec_query_plan).

Check waits: sys.dm_os_wait_stats for dominant waits.

Verify IO: PerfMon counters for disk latency (Avg. Disk sec/Read and Avg. Disk sec/Write).

Inspect indexes: missing, fragmented, or unused indexes via DMVs (sys.dm_db_index_usage_stats, sys.dm_db_index_physical_stats).

Review parameter sniffing: try RECOMPILE hints or optimize for parameters or use plan guides if necessary.

Test rollback plan: restore from backup to a test server and reproduce issue.
