Update SAP BW with SUM on AS400 error in Downtime

Hi Guys,

We are about to update our SAP BW System

In the Downtime at the Phase MAIN_SWITCH/SUBMOD_SWITCH_KERNEL/KX_SWITCH_DIAG we get the folowing error.

set: Cannot list Directory '\\C0SRV6011\SAPMNT\BDA\SYS\exe\uc\NTAMD64' : No such file or Directory

We have tryed to copy the hole directory to the point SUM searchs but with no success.

We also have restarted the SUM process "SAPup"

The System is an AS400 System with an Netweaver BW on top and we noe want to upgrade to NW 7.5 and latest BW.

Thanks in advance

Vincenzo Ferrarese
