I have a specific scenario to ask questions; however, my goal to identify the general requirement or best practice when upgrading major version or service pack.
We want to upgrade SQL Server 2016 SP1 (GDR "Train") to SQL Server 2017 Latest CU (CU15). We will perform New Installation with Migration Upgrade.
The questions are as follows, please indicate as well ALL that apply as well a) REQUIRED b) BEST PRACTICE c) NOT REQUIRED d) NOT RECOMMENDED:
1. Should we perform mini-upgrade/CU Patch IN PLACE for SQL Server 2016 SP1 (GDR "Train) to SQL Server 2016 SP2 latest CU (CU7)PRIOR TO Migration Upgrade?
2. If yes to above, should we apply latest CU on SQL Server 2016 SP1 (GDR "Train") prior to SQL Server 2016 SP2 mini-upgrade?
PLEASE EXPLAIN?
Don't forget to apply a-d from above for each question.
