    Hello. For example you can say your OS )) All instances are on separate hosts ? OS are the same for all instances ?

    For example if you use UNIX :

    Per my opinion the safest way is backup old kernel , CP new files in /sapmnt/SID/exe folder on oll hosts where

    application servers is installed , and start it one by one after central instance.

    I know sapcpe can copy kernel in many situations (including remote copy if configured) but i do it manually to avoid problems.

    Regards.
