Gap between preprocessing phase and system downtime

[former_member201054]

Hi Experts,

I have completed preprocessing phase on SCM 7.0 EHP3 upgrade(nZDM) in production system and now there are 5 more days to go for execution phase ( downtime).. since the system is in running status to the users in between and shadow instance has been created now..what should do I have monitor in the system daily before to go for the execution phase

I would appreciate your inputs and any relevant documents.

Thanks in advance

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
