IS the new SharePoint 2013 Cumulative updates include all previous Cumulative updates and Service packs?

Question

Hi the new SharePoint 2013 Cumulative updates include all previous Cumulative updates and Service packs because in my farm when I join the new server I am facing issues, when I install March 12, 2019, cumulative update for SharePoint Enterprise Server 2013 (KB4462219) and run the Configuration wizard it showing missing locally below service pack 1.

Service Pack 1 for Microsoft SharePoint Server 2013 (KB2880552)

Answer 1

You can check the KB of the CU to check if it includes all previous Cumulative updates and security updates like this.

If it contains, you will see like the below:

But, if you install a CU after SP1 for SharePoint 2013, you need to make sure you have installed SP1 which is a prerequisites.
