There is a SharePoint 2013 Farm where a SharePoint Cummulative Update (CU) / Uber Package needs to be installed. The SharePoint Farm consists of the following 3 servers:
1 Web Front End Server
1 Application Server
1 SQL Server.
As I understand, the CU (Uber Package) needs to be installed on the WFE server and on the APP server. The SQL Server SharePoint databases will be updated by running the SharePoint Products and Configuration Wizard. The CU does not need to run on the SQL Server.
In order to save time, is it possible to install the CU (Uber Package) on the Web Front End Server and on the Application Server at the same time, or should I install it seperatly on each server (first WFE, second APP)?
Thank you in advance.
