• Key Concepts: 
  A rolling kernel switch is a process used in SAP Client/Server Technology (BC-CST) to update the system kernel without having to restart the entire system. This process allows for a smooth transition from one version of the kernel to another, while still allowing the system to remain operational. 
  
  How to use it: 
  The rolling kernel switch process is initiated by the SAP system administrator. The administrator will first install the new kernel version on the server, and then initiate the rolling kernel switch process. This process will then update each client connected to the server with the new kernel version, one at a time. Once all clients have been updated, the new kernel version will be active and operational. 
  
  Tips & Tricks: 
  When performing a rolling kernel switch, it is important to ensure that all clients are connected to the server and that they are running compatible versions of the software. Additionally, it is important to ensure that all clients are running the same version of the software before initiating the rolling kernel switch process.
