SAP BI 4.2 sp9 to SAP BI 4.3 sp2 - IN PLACE Installation

Dear All,

I'm going to do an "IN PLACE" Installation from "SAP BI 4.2 sp9" to "SAP BI 4.3 sp2".

What I have to do in order to achieve this target ? I have to run "setup.sh" from SAP BI 4.3 installation files ? or Other steps are required ?

Please share, if exist, an "How-to" or "Best Practice" to follow about this argument.

Any help is appreciated

Best regards,

MJ
