Hello Vipin,
I was confused by the question:
"But I wanted to know, if still need to follow the same note, even to perform the Kernel update of liveCache 7.9, build 10 to iveCache 7.9, build 10."
A you planning to update just LCAPPS buiuld which were compiled with the same liveCache version?
In general please see the SAP note:
1855747 - Overview: Update of SAP MaxDB/liveCache/CS in MSCS environm.
< if Source Version 7.9 build x to Target version: 7.9 build y => 5. >
Regards, Natalia Khlopina
