Hello,
my logshipping primary database instance is running on Microsoft SQL Server 2012 (SP4-GDR) (KB4057116) - 11.0.7462.6 (X64) and secondary is running on Microsoft SQL Server 2012 (SP4) (KB4018073) - 11.0.7001.0 (X64).
we have to apply Security update for SQL Server 2012 Service Pack 4 – 4532098( (QFE): Feb 11, 2020.
can we apply SQL security patch on SQL instance of secondary logshipping database without applying on primary? or what will be sequence?
