I would appreciate your inputs and any relevant documents.

    Hi Daniel ,

    Make sure that you have a backup of all the Filesystem ( Including the SUM directory , Profiles and the Kernel )

    Is there a change management freeze ? Ensure the transport system is freezed ( If possible ) , No new transports should be imported into the system [ Unless and until is is an Emergency transport ]

    Make sure that any changes to OS or DB , including SAPGUI is not done which is not planned .

    Other than that all BASIS regular checks like SM21, ST22 , Performance etc should suffice .

    Thanks ,

    Manu
