I have updated support pack 00 to 09 on our new portal sandbox 7.3.1 using SUM tool
Do I need to follow any other medthod?
I generated Stack xml file from Solution Manager and selected it but got error that "The Directory contains invalid archives" then
I selected manually prepared directory i.e. /usr/sap/trans/EPS/in/ where the all patches have been placed.
SUM finshed successully without any errors, but only few components have been updated and Kernel upgraded successully
